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

Inorganic Chemistry, Год журнала: 2024, Номер 63(14), С. 6500 - 6513

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.

This review delves into the underlying principles, advantages, challenges, and recent developments in photoelectrocatalysis (PEC) processes for wastewater treatment green hydrogen production. PEC is an emerging technique that holds great promise addressing two critical challenges simultaneously, namely, degradation of industrial pollutants generation clean energy form gas. In years, many studies have explored use photoanodes to harness solar treatment. These facilitate breakdown contaminants, while cathode concurrently produces hydrogen. The enables production both water gas from wastewater. dual benefit makes it attractive avenue sustainable generation. process capitalizes on constructive interaction between electrochemical reactions photocatalysis. Solar efficiently converted electron-hole pairs, which play a pivotal role water-splitting occurring at electrode surfaces. Achieving best performance involves scrutiny various parameters, including catalyst loading, pH, light intensity, electrolyte composition. photoelectrocatalytic system shows commendable stability durability during extended operation, reinforcing its practical applicability. provides comprehensive overview process, materials, optimization strategies, driving efficiency. Considering potential benefits costs larger scale underscores significance environmental concerns energy-related issues concurrently. Therefore, promising pathway toward energy, bridging gap stewardship technological advancement.
