The environment being surrounded by accumulated durable waste organic compounds has become a critical crisis for human societies. Generally, effluents of industrial plants released into the water source and air are removed some physical chemical processes. Utilizing photocatalysts as cost-effective, accessible, thermally/mechanically stable, nontoxic, reusable, powerful UV-absorber creates new gateway toward removal dissolved, suspended, gaseous pollutants even in trace amounts. TiO2 ZnO two prevalent field removing contaminants from wastewater air. Structural modification with metals, nonmetals, metal ions, other semiconductors reduces band gap energy agglomeration increases affinity composite structures to expand their usability on an scale. This extent light absorbance improves photocatalytic efficiency. Selecting suitable synthesis method is necessary prepare target photocatalyst distinct properties such high specific surface area, numerous functional groups, appropriate crystalline phase. In this Review, significant parameters TiO2- ZnO-based discussed detail. Several proposed mechanistic routes according provided. Some electrochemical analyses using charge carrier trapping agents delayed recombination help plot direction photoexcited species (electron–hole pairs) design more effective processes terms cost-effective photocatalysts, saving time increasing productivity.

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.
