A review on exploration of Fe2O3 photocatalyst towards degradation of dyes and organic contaminants

Surface plasmon resonance triggered promising visible light photocatalysis of LiNbO3 ceramic supported Ag nanoparticles

“…Moreover, these organic dyes disturb aquatic life by causing eutrophication 3 . Nowadays, the photocatalysis process has emerged as an effective solution to remove harmful organic dyes pollutants from the water sources 4–6 . Many semiconductors with wider band gap values such as ZnO, 7 SrTiO 3 , 8 TiO 2 9 etc.…”

Enhancement of photo-Fenton catalytic activity with the assistance of oxalic acid on the kaolin–FeOOH system for the degradation of organic dyes

“…7 Recently, advanced oxidation processes (AOPs), characterized by the production of highly reactive radicals ($OH), have been widely employed in the treatment of organic wastewater, especially non-biodegradable and persistent ones, due to their strong oxidation capacity. 8,9 Among the AOPs, the photo-Fenton process can effectively promote the decomposition of hydrogen peroxide and the reduction of ferric ions, which facilitates the formation of $OH.…”

Review on heterogeneous photocatalytic disinfection of waterborne, airborne, and foodborne viruses: Can we win against pathogenic viruses?

“…The heterogeneous photocatalytic performance of viral disinfection principally pertains to the capability for retardation of e − /h + pairs from recombination and the ability to fully utilize sunlight. Regrettably, the photocatalytic ability of most semiconductors is trivial because of several disadvantages including poor capability for e − /h + separation, fast recombination of charges, and low utilization efficiency of solar light [47] , [48] . Up to now, diverse photocatalysts such as g-C 3 N 4 , CuO, ZnO, TiO 2 , and Ag 3 PO 4 prepared with different morphologies, structures, and procedures have been used for the inactivation of viruses due to their nonhazardous nature and high stability [49] , [50] , [51] .…”
