Summary: A brand-new catalyst of C-modified and N-doped TiO2 (T3FN1) was synthesized via the hydro-thermal method using Tetrabutyl titanate (TBOT) and feathers of chicken as the precursor. The catalyst exhibited a unique three-dimensional folded rod-shaped micron structure, thanks to the abundant distribution of TiO2 nanoparticles (anatase phase) around the outer surface of the feathers template. Under visible light illumination for 30 minutes, the degradation rate of TCH reached 89.8% with T3FN1, which was 1.52 times and 2.62 times higher than that of TiO2 without template (T-3) and P25, respectively. Mechanism studies revealed that the chicken feathers served as natural organic templates to enhance the dispersity of TiO2 and nitrogen in feathers was directly doped into TiO2 to improve the catalysts' response to visible light. Furthermore, the carbon in the chicken feathers acted as a transmission medium for electric charges, promoting the spatial separation of photo-induced carriers. Moreover, T3FN1 showed wide adaptability and stability within a pH range, with the degradation rate of TCH still reaching 83.15% after 5 cycles. Overall, due to its unique structure and photocatalytic performance, the catalyst holds great potential for practical wastewater treatment.

Summary: In this study, the role of oxygen vacancies (V-O) in semiconductors' photocatalytic hydrogen evolution reaction (PHER) activities was investigated using BiCeOS with different V-O abundances and n(Ce3+/Ce4+) amounts. The results showed that V-O converted tetravalent cerium into trivalent cerium to maintain electrical neutrality. BiCeOS with rich V-O and higher n(Ce3+/Ce4+) amounts exhibited better visible light-excited photocurrent and easier photoinduced charge separation. DFT calculations revealed that BiCeOS with rich V-O strongly interacted with water to form a distorted water molecule, resulting in excellent visible light PHER activities.

Summary: In this study, we demonstrated the incorporation of S2- anion into BiVO4 to convert an oxidative-type photocatalyst into a reductive-type sulfo-oxide photocatalyst, which showed efficient N2 fixation under ambient conditions. The doped BiVOS-2 catalyst exhibited the highest NH3 production rate, durable stability, and good conversion efficiency under solar light irradiation. Density functional theory (DFT) calculations revealed that the S2- doping enhanced adsorption energy, elongated the N=N bond of the adsorbed N2 molecule, and facilitated electron transfer, leading to excellent N2 fixation activity. This study provides a promising method to extend the applications of oxidative-type catalysts by converting them into reductive catalysts.
