CH3OH selective oxidation to HCHO on Z-scheme Fe2O3/g-C3N4 hybrid: The rate-determining step of C-H bond scission

Sheng Huang et al.

Summary: This study presents a direct Z-scheme system (ZOF@CN NTs) consisting of 1D nanotubes oxygen-deficient alpha-Fe2O3 and g-C3N4, which shows a significantly enhanced activity and selectivity for PEC CH3OH oxidation to HCHO. The mechanism of CH3OH oxidation to HCHO on the Z-scheme ZOF@CN NTs photoanode involves key steps such as O-H bond scission and C-H bond scission, with N atoms from g-C3N4 playing a crucial role due to their higher electronegativity compared to O atoms. This work provides a solid foundation for understanding Fe2O3-based Z-scheme system photoanodes for CH3OH oxidation to HCHO.

Molybdenum Dioxide Nanoparticles Anchored on Nitrogen-Doped Carbon Nanotubes as Oxidative Desulfurization Catalysts: Role of Electron Transfer in Activity and Reusability

Juncong Zou et al.

Summary: The electron transfer between metal-oxides and supports greatly impacts the performance of catalysts in oxidative desulfurization (ODS), with molybdenum dioxide with oxygen vacancies (V-O-MoO2) catalysts anchored on electron-rich nitrogen-doped carbon nanotubes (NC) showing excellent ODS activity and reusability. By promoting dispersion of V-O-MoO2 and reducing the bond energy of the Mo-O bond, the strong electron-donating effect of NC on V-O-MoO2 enhances exposure of active sites and enriches oxygen vacancies, leading to effective desulfurization.
