Fe-VS Electrocatalyst with Organic Matrix-Mediated Electron Transfer for Highly Efficient Nitrogen Fixation.

Electrochemical N fixation is considered to be a promising alternative to Haber-Bosch technology. Inspired by the composition and structure of natural nitrogenase, Fe-doped VS nanosheets were prepared via one-step solvothermal method. The electron transfer system mediated by organic conductive polymer (1-AAQ-PA) was constructed to promote the electron transfer between Fe-VS nanosheets and the electrode in electrocatalytic N reduction reaction (NRR).

Nano-zero-valent iron and MnO selective deposition on BiVO decahedron superstructures for promoted spatial charge separation and exceptional catalytic activity in visible-light-driven photocatalysis-Fenton coupling system.

Novel nano-zero-valent iron (Fe)/MnO/BiVO ternary magnetic assemblies are fabricated through hydrothermal and photo-deposition strategy. The assemblies are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, photoluminescence, X-ray photoelectron spectroscopy, and UV-vis diffuse reflectance spectroscopy. Fe as a reduction cocatalyst are deposited on surface of monoclinic BiVO decahedron supersturcture.

Oxygen-Doped MoS Nanospheres/CdS Quantum Dots/g-CN Nanosheets Super-Architectures for Prolonged Charge Lifetime and Enhanced Visible-Light-Driven Photocatalytic Performance.

Oxygen-doped MoS nanospheres/CdS quantum dots/g-CN nanosheets are synthetized through hydrothermal and chemical bath deposition-calcination processes. The prepared materials are characterized by X-ray diffraction transient-state photoluminescence spectra, transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, and electrochemical experiment. These results show that the ternary composite material has longer lifetime of photogenerated carriers and more active sites, thereby enhancing photocatalytic performance.

Synergistic effect of surface plasmon resonance, Ti and oxygen vacancy defects on Ag/MoS/TiO ternary heterojunctions with enhancing photothermal catalysis for low-temperature wastewater degradation.

Ag/MoS/TiO ternary heterojunctions are fabricated through hydrothermal and photo-deposition process combine with in-situ solid-state chemical reduction approach. The prepared materials are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, photoluminescence, and X-ray photoelectron spectroscopy. The results show that the ternary heterojunctions doped with Ti are formed, meanwhile, Ag nanoparticle and MoS nanosheets are anchored on surface of TiO nanobelts simultaneously.

Wide spectral response photothermal catalysis-fenton coupling systems with 3D hierarchical FeO/Ag/BiMoO ternary hetero-superstructural magnetic microspheres for efficient high-toxic organic pollutants removal.

3D hierarchical FeO/Ag/BiMoO magnetic microspheres are fabricated through hydrothermal-photoreduction strategy, which fabricate an advanced photocatalytic-Fenton coupling system. The HO produced by photocatalysis could form the photo-Fenton system when combined with FeO under light illumination. The introduction of Ag nanoparticles could induce the localized surface plasmon resonance (LSPR), which provides "hot electrons" for promoting photocatalysis.
