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.
