Due to the depletion of fossil fuels and their-related environmental issues, sustainable, clean, renewable energy is urgently needed replace fuel as primary resource. Hydrogen considered one cleanest energies. Among approaches hydrogen production, photocatalysis most sustainable solar technique. Considering low cost fabrication, earth abundance, appropriate bandgap, high performance, carbon nitride has attracted extensive attention catalyst for photocatalytic production in last two decades. In this review, nitride-based system, including catalytic mechanism strategies improving performance discussed. According processes, strengthened catalysts particularly described terms boosting excitation electrons holes, suppressing carriers recombination, enhancing utilization efficiency photon-excited electron-hole. Finally, current trends related screening design superior systems are outlined, development direction clarified.

Photocatalysis Meets Piezoelectricity in a Type-I Oxygen Vacancy-Rich BaTiO₃/BiOBr Heterojunction: Mechanism Insights from Characterizations to DFT Calculations

It is a challenging task to design piezoelectric photocatalyst with excellent performance under mechanical agitation instead of ultrasonic irradiation. Integrating vacancy defects into heterojunction seems be an effective strategy for synergistically increasing its piezo-photocatalytic performance. For this goal, two-step hydrothermal method was adopted architect type-I oxygen-vacancy-rich BaTiO3/BiOBr surge the degradation Rhodamine B (RhB) combined action simulated sunlight irradiation and agitation. Various instrumental techniques demonstrated formation high crystallinity. The existence surface oxygen vacancies confirmed by XPS EPR tests. PFM results manifested that had properties, response value 30.31 pm V–1. Comparative experiments indicated RhB efficiency piezo-photocatalysis over largely exceeded total sum those piezocatalysis photocatalysis. h+, ·O2–, 1O2 were dominant reactive species degradation. improved separation photogenerated charges verified electrochemical measurements. DFT calculations polarization BaTiO3 could affect electronic band structure BiOBr. This work will provide comprehensive insights mechanism at microcosmic level help develop new-styled photocatalysts.
