“…Matsunaga et al found in 1985 that utilizing TiO 2 as a photocatalyst may kill bacteria in water, so opening up a new route for photocatalytic inactivation of microorganisms. (AbuKhadra et al 2020 ) Aside from the breakdown of various organic and inorganic molecules, additional studies have revealed that ROS oxidized the cell membrane, resulting in the release of nucleic acids, proteins, and specific cations, eventually leading to bacterial cell death (Mkhalid et al 2020 ). Kim et al used a Co-doped BiVO 4 technique to pretreat wastewater.…”

Wastewaters often contain toxic organic pollutants with a possible adverse effect on human health and aquatic life upon exposure. Persistent organic pollutants such as dyes and pesticides, pharmaceuticals, and other chemicals are gaining extensive attention. Water treatment utilizing photocatalysis has recently received a lot of interest. Photocatalysis is cutting-edge, alternative technology. It has various advantages, including functioning at normal temperatures and atmospheric pressure, cheap prices, no secondary waste creation, and being readily available and easily accessible. This review presented a comprehensive overview of the advances in the application of the photocatalytic process in the treatment of highly polluted industrial wastewater. The analysis of various literature revealed that TiO 2 -based photocatalysts are highly effective in degrading organic pollutants from wastewater compared to other forms of wastewater treatment technologies. The electrical structure of a semiconductor plays a vital role in the photocatalyst's mechanism. The morphology of a photocatalyst is determined by the synthesis method, chemical content, and technical characteristics. The scaled-up of the photoreactors will significantly help in curbing the effect of organic pollutants in wastewater.

“…This leads to the presence of viruses in wastewater that causes a variety of gastrointestinal diseases. Their chemical stability and biodegradation resistance make pesticides even more harmful, and photocatalytic wastewater technology can cope with those challenges . Concerning the inactivation of microorganisms, photocatalysis can provide reactive oxygen species (ROS) to destruct proteins and other macromolecules and finally cause cell death …”

Removal of heavy metals in wastewater treatment is crucial to protect the environment, wildlife, and human health. Various techniques have been developed focusing on removal of heavy metal ions, pharmaceuticals, and other contaminants from different wastewater sources. The main methods include adsorption, filtration, ion exchange, electrochemical, reverse osmosis, precipitation, flotation/coagulation/ flocculation, and photocatalytic-based treatments. This paper comprehensively assesses the sustainability of those common technologies used for wastewater process treatment. The sustainability profile depends mostly on the exact approach followed for each technology, including its energy consumption, type of radiation (where appropriate), auxiliary materials used (e.g., catalysts, adsorbents), and further specific experimental process settings. Thus, while sustainability inevitably provides a multifaceted answer, the review finally aims for sustainability benchmarking of all technologies, by compressing the manifold outcomes toward a compact information set, such as a table and radar plot.

“…Photocatalytic degradation of dimethenamid-P herbicide was performed by mesoporous Ag/Ag 2 O-TiO 2 p-n heterojunction under visible light. The photoactivity results showed the complete removal of imazapyr destruction after 180 min [ 93 ]. Photocatalytic degradation of profenofos and triazophos residues in the Chinese cabbage using Ce-doped TiO 2 was also studied [ 94 ].…”
