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.

Heterojunction photocatalysts are critical for facilitating long-term photoinduced carrier separation and enhancing single photocatalyst photocatalytic performance. As part of the present study, calcium stannate (CaSnO3, CSO) was produced using a simple low-cost auto-combustion method, CaSnO3/g-C3N4 (CSO/CN) nanocomposites with different CSO contents were prepared co-precipitation method aided by ultrasound. An investigation erythrosine (ER) eryochrom black T degradation capacities CSO, CN, several CSO/CN carried out. According to results, rate affected dye type, amount catalyst, as well concentration ER. With 70 mg (0.1:1), nanocomposite 10% demonstrated greatest efficiency, which resulted in 86.2% ER being destroyed. Scavenger experiments revealed that superoxide radicals exhibited exceptional characteristics photoreactions. A higher proficiency (86.2%) contributed highest constant (k = 0.022 min−1), according kinetics study. result these findings, there is potential be used water treatment applications.

Modern society pays further and attention to environmental protection the promotion of sustainable energy solutions. Heterogeneous photocatalysis is widely recognized as one most economically viable ecologically sound technologies combat pollution global crisis. One challenge finding a suitable photocatalytic material for an efficient process. Inorganic nanotubes have garnered potential candidates due their optoelectronic properties, which differ from bulk equivalents. Among them, clay (halloysite, imogolite, chrysotile) are attracting renewed interest applications thanks low production costs, unique physical chemical possibility functionalize or dope structure enhance charge-carriers separation into structure. In this review, we provide new insights these inorganic in photocatalysis. We first discuss structural morphological features nanotubes. Applications photocatalysts based on across range reactions, including decomposition organic pollutants, elimination NOx, hydrogen, disinfection bacteria, discussed. Finally, highlight obstacles outline avenues advancing current system Our aim that review can offer researchers opportunities advance research field nanotubes-based with other vital future.
