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.

Photocatalytic N2 conversion to NH3 is a green, sustainable pathway with renewable energy sources and carbon neutrality. In this research, ternary TiO2 QDs/TiO2 OVs/Cu5FeS4 nanocomposites were prepared by an easy affordable procedure utilized produce clean ammonia without sacrificial agent. The amount of produced green the optimum nanocomposite achieved was 17,274 μmol L–1 g–1, which approximately 20.9, 6.48, 4.45, 2.26, 1.45 times higher than those commercial TiO2, QDs, OVs, Cu5FeS4, OVs photocatalysts, respectively. Lattice compatibility through developed homojunction within integration Cu5FeS4 nanoparticles led establishment double S-scheme homo/heterojunction system, improved photocatalytic activity maintaining electrons holes high oxidation reduction power greatly reduced recombination charges, acceleration charge transfer migration. Besides, promoted surface area compared pure components, introducing oxygen vacancies, reducing particle size boosted NH3. results research are basis for rational design homojunction/heterojunction visible-light-responsive systems nitrogen fixation reactions.
