    Hierarchical nano-vesicles with bimetal-encapsulated for peroxymonosulfate activation. Singlet oxygen-dominated oxidation process
    (Elsevier, 01.04.2022) Lyu, Zhiping; Xu, Menglu; Wang, Jinnan; Li, Aimin; Corvini, Philippe [in: Chemical Engineering Journal]
    Hierarchical nano-vesicles with bimetal-encapsulated (FeCu1.5O3@NV) was designed for peroxymonosulfate (PMS) activation with the 1O2-dominated oxidation process. Different from previous core–shell metal-loaded catalysts, FeCu1.5O3 was encapsulated in hollow zeolite spheres, and these zeolite sphere units assembled to construct hierarchical nano-vesicles. Owning to mesoporous shell and abundant interior cavity, FeCu1.5O3@NV could enrich reactants in cavity for enhancing the contact with active sites. The flexible surface of bimetal oxides strengthened the affinity with surface adsorbates and substrates, accelerating the electron transfer between reactants. DFT calculation indicated that FeCu1.5O3@NV possessed strong binding affinity for BPA and PMS, facilitating PMS activation and BPA degradation inside of hollow sphere units. Being attributed to the synergistic effect of bimetal redox couples and hierarchical nano-vesicle structure, large amounts of 1O2 could be generated through two pathways for BPA degradation. The first pathway is the reaction between bimetal redox couples and PMS, and the second is the chain reaction of O2•−. Due to bimetal oxides uniformly encapsulated in hierarchical nano-vesicles, FeCu1.5O3@NV possessed high catalytic stability with negligible metal leaching. Even after 5 cycles, BPA removal could still remain 100%.

    BiOBr/ Bi4O5Br2/PDI constructed for visible-light degradation of endocrine disrupting chemicals. Synergistic effects of bi-heterojunction and oxygen evolution
    (Elsevier, 01.04.2022) Wang, Haoyi; Zhou, Ye; Wang, Jinnan; Li, Aimin; Corvini, Philippe [in: Chemical Engineering Journal]
    To remove endocrine disrupting chemicals (EDCs), visible-light response photocatalyst BiOBr/Bi4O5Br2/perylene diimide (PDI) with bi-heterojunction was constructed. Under visible-light irradiation, BiOBr/Bi4O5Br2/PDI could degrade 90% Bisphenol A (BPA) within 75 min, while degrade 100% 17α-ethynyl estradiol (EE2) and 17β-estradiol (E2) within 15 min. Radicals quenching experiment and EPR indicated both •O2– and holes were the main substances for EDCs degradation, and the possible degradation pathway of EDCs are proposed based on the LC-MS analysis results. In the composite of BiOBr/Bi4O5Br2/PDI, the matching energy band structure between Bi4O5Br2 and BiOBr facilitated the formation of heterojunction for strengthening the space charge separation. Meanwhile, PDI with strong photosensitivity combined with BiOBr/Bi4O5Br2 not only enhanced visible-light photocatalytic activity but also broadened the light-harvesting range. Owning to the unique one-dimensional conjugated structure and internal electric field effect, PDI could also promote the photo-carriers transfer and separation. With the bi-heterojunction effect, photo-generated electrons were transferred to BiOBr conduction band while holes were accumulated on PDI valence band. Simultaneously, holes could oxidize water with the production of oxygen following being reduced to •O2– by photo-generated electrons. Even under oxygen-poor conditions, the production of •O2– can reach 32.7 × 10-5mol•g−1•h−1, resulting in more than 85% BPA degradation within 75 min.

    Ultrafine-Mn2O3@N-doped porous carbon hybrids derived from Mn-MOFs: Dual-reaction centre catalyst with singlet oxygen-dominant oxidation process
    (Elsevier, 2022) Xie, Zhiqun; Lyu, Zhiping; Wang, Jinnan; Li, Aimin; Corvini, Philippe [in: Chemical Engineering Journal]
    Ultrafine-Mn2O3@N-doped porous carbon hybrids [Mn2O3@NC] derived from Mn-MOFs was constructed with 1O2 and O2−• as main Reactive oxygen species (ROS). Cation-π bonds and N-Mn complexation induced the formation of electron-rich Mn centre which provided electron for peroxymonosulfate activation to produce radicals, accompanying with generation of 1O2 via chain reaction. Notably, the porous structure of N-doped carbon shell could not only facilitate free radical recombination for generation of 1O2 but also provide adsorption sites for organics. On the other hand, as electron-poor centre, N-doped carbon shell could improve the electrons transfer from organic intermediate radicals to electron-rich Mn centre via π -π reaction, C-O-Mn and C-N-Mn bonds, which promote the redox of Mn to avoid peroxymonosulfate invalid decomposition. Being attributed to synergistic effects of dual-reaction centres and strong oxidation ability of 1O2, Mn2O3@NC achieved high mineralization of BPA at low-dose peroxymonosulfate (0.033 g/L).

    Engineering efficient hole transport layer Ferrihydrite-MXene on BiVO4 photoanodes for photoelectrochemical water splitting: Work function and conductivity regulated
    (Elsevier, 2022) Bai, Weihao; Zhou, Ye; Peng, Gang; Wang, Jinnan; Li, Aimin; Corvini, Philippe [in: Applied Catalysis B: Environmental]
    Although great interest is focused on development of semiconductor photoanodes for efficient photoelectrochemical (PEC) water splitting, the pressing bottleneck to address the intrinsic charge transport for enhancement of PEC performance still remains to be resolved. Herein, hole transport layer (Fh-MXene) constructed by doping of MXene (Ti3C2) in Ferrihydrite (Fh) is loaded on BiVO4 photoanode. This novel BiVO4@Fh-MXene photoanode achieves high current density of 4.55 mA cm−2 at 1.23 V versus reversible hydrogen electrode (vs. RHE), exhibiting excellent photostability. From electrochemical analysis and density functional theory calculations, high PEC performance is ascribed to incorporation of Fh-MXene as hole transport layer, enhancing conductivity and water oxidation reaction. Notably, MXene can improve band alignment of BiVO4/Fh-MXene interface by tuning work function, which strengthens the built-in electric field for more efficient hole extraction. This work provides a simple method to design photoanodes with efficient charge transport layers for feasible PEC water splitting application.

    High efficient photocatalytic reduction of nitrate to N2 by Core-shell Ag/SiO2@cTiO2 with synergistic effect of light scattering and surface plasmon resonance
    (Elsevier, 01.07.2021) Corvini, Philippe; Hou, Ziang; Chu, Jiangfeng; Liu, Cong; Wang, Jinnan; Li, Aimin; Lin, Tong [in: Chemical Engineering Journal]
    Photocatalytic denitrification has attracted great attention owing to its high efficiency and environmentally friendly features. However, selectively photocatalytic reduction of high concentration nitrate to N2 is still a challenging problem due to the competition of photons between nitrate and photocatalysts. Herein, the Ag/SiO2 core encapsulated in the crystalline TiO2 shell (Ag/SiO2@cTiO2) was constructed for improvement of photocatalytic denitrification. Finite difference time domain (FDTD) simulation demonstrated that strong light scattering improved light harvesting via optical confinement. Meanwhile, surface plasmon resonance and electron sink effect of Ag not only enhanced the photogenerated electrons density but also promoted charge carriers separation of Ag/SiO2@cTiO2. More importantly, ecb− of TiO2-shell could be immediately transferred to Ag to keep the balance between Ag0 and Ag+, which contributed to the good stability of Ag/SiO2@cTiO2. 95.8% nitrate (C0 = 2000 mg/L) was removed by 5 wt%Ag/SiO2@cTiO2 with N2 selectivity of 93.6% within 4 h. Even after five cycles, 5 wt%Ag/SiO2@cTiO2 still remained high photocatalytic denitrification efficiency (92.2%). Notably, since TiO2-shell prevented the reaction between Ag and Cl−, more than 92% nitrate could be removed within 5.3 h in the presence of high concentration Cl−.

    Long-term field study on fate, transformation, and vertical transport of tetrabromobisphenol A in soil–plant systems
    (American Chemical Society, 21.03.2021) Corvini, Philippe; Songfeng, Wang; Xuan, Wu; Rong, Guo; Wang, Qilin; Guo, Hongyan; Sun, Feifei; Ji, Rong [in: Environmental Science & Technology]
    Soil contamination with tetrabromobisphenol A (TBBPA) has been an environmental concern for many years, but in situ studies of the fate and potential risk of TBBPA are lacking. In this study, we investigated the dissipation, metabolism, strong alkali-hydrolytic (SAH-TBBPA), and vertical movement of TBBPA in the field with and without rice-wheat rotation and reed growth for 1225 days. After 342 days of incubation, 21.3% of the TBBPA remained in the surface soil accompanied by obvious leaching to deeper soil layers in the first 92 days. By day 1225, TBBPA was nearly absent from the surface soil layer. A very low amount of SAH-TBBPA (2.31–3.43 mg/kg) was detected during the first 342 days of incubation. In the surface soil, five metabolites were identified that represented four interconnected pathways: oxidative skeletal cleavage, O-methylation, type II ipso-substitution, and reductive debromination. Both rice–wheat rotation and monocultural reed growth accelerated TBBPA removal in the field by stimulating the anaerobic debromination and aerobic O-methylation, especially the oxidative skeletal cleavage of TBBPA in the rhizosphere soil. Though far from comprehensive, our study investigated the natural attenuation and metabolism of TBBPA in situ and the influence by crops to estimate the environmental risk of TBBPA in a field scale.
