Summary: This study investigates heterogeneous Fenton catalysts based on iron-oxides and finds that nano-sized amorphous iron-oxide particles have high degradation activity towards pollutants with minimal consumption of H2O2. The mechanism involves complexation of H2O2 to the catalytic sites on the iron oxide surface, leading to oxidation and mineralization of pollutants through the production of reactive species such as •OH and O-1(2).

Summary: Designing nanostructured photoelectrodes with unique morphology and suitable band structure is essential for potential photoelectrochemical applications. In this study, compact Sn3O4 nanoflakes with a smooth surface were grown directly on a carbon paper substrate using a simple hydrothermal method. The molar ratio of Sn2+ and Sn4+ ions in the Sn3O4 nanoflakes was modulated through subsequent H2O2-assisted hydrothermal treatment. The effect of different molar ratios on the energy band and the evolution of the surface morphology of the nanoflakes were systematically investigated. By utilizing the H2O2-assisted hydrothermal process, a highly efficient photoelectrode based on Sn3O4 nanoflakes was prepared, exhibiting a larger active surface area and suitable band structure, leading to excellent photocurrent response and photocatalytic performance for H2 production.

Summary: The slow cycling efficiency of reducing Fe3+ to Fe2+ is the main factor limiting the decomposition of H2O2 in the Fe3+/H2O2 reaction. The addition of tungsten disulfide (WS2) as a co-catalyst greatly enhances the reaction rate-limiting step and H2O2 decomposition, leading to effective degradation of acetaminophen (APAP). WS2 promotes the conversion of Fe3+ to Fe2+ mainly on its surface through redox reactions with exposed W4+ active sites and proton-bound unsaturated S atoms. This study provides a new perspective for improving the efficiency of Fe3+/H2O2 and highlights the involvement of transition metal sulfides in advanced oxidation processes (AOPs).
