Nowadays, the increasing emergence of antibiotic-resistant pathogenic microorganisms requires search for alternative methods that do not cause drug resistance. Phototherapy strategies (PTs) based on photoresponsive materials have become a new trend in inactivation due to their spatiotemporal controllability and negligible side effects. Among those phototherapy strategies, photocatalytic antimicrobial therapy (PCAT) has emerged as an effective promising strategy recent years. In process treatment, are excited by different wavelengths lights produce reactive oxygen species (ROS) or other toxic killing various microbes, such bacteria, viruses, fungi, parasites, algae. Therefore, this review timely summarizes latest progress PCAT field, with emphasis development antimicrobials (PCAMs), underlying mechanisms, design multiple practical applications local infections therapy, personal protective equipment, water purification, coatings, wound dressings, food safety, antibacterial textiles, air purification. Meanwhile, we also present challenges perspectives widespread implementation therapeutics. We hope result review, will flourish weapon against antibiotic

Photodegradation is an efficient strategy for the removal of organic pollutants from wastewater. Due to their distinct properties and extensive applications, semiconductor nanoparticles have emerged as promising photocatalysts. In this work, olive (Olea Europeae) fruit extract-based zinc oxide (ZnO@OFE NPs) were successfully biosynthesized using a one-pot sustainable method. The prepared ZnO NPs systematically characterized UV-Vis, FTIR, SEM, EDX XRD photocatalytic antioxidant activity was evaluated. SEM demonstrated formation spheroidal nanostructures (57 nm) ZnO@OFE analysis confirmed its composition. FTIR suggested modification/capping with functional groups phytochemicals extract. sharp reflections revealed crystalline nature pure most stable hexagonal wurtzite phase. synthesized catalysts evaluated by measuring degradation methylene blue (MB) methyl orange (MO) dyes under sunlight irradiation.

Review on ZnO hybrid photocatalyst: impact on photocatalytic activities of water pollutant degradation

Reviews in Inorganic Chemistry, Journal Year: 2016, Volume and Issue: 36(2)

Published: Jan. 1, 2016

Abstract Zinc oxide (ZnO) is one of the most widely used benchmark standard photocatalysts in field environmental applications. However, large band gap ZnO and massive recombination photogenerated charge carriers, especially its nanosize, limit overall photocatalytic efficiency. This can be further overcome by modifying electronic structure hybridization with a narrow material, including metal, metal oxide, carbon based, polymeric based. Indeed, respective materials contributed to sensitizer shifting absorption wavelength visible region spectrum. review encompasses several advancements made mentioned aspects, also some new physical insights related transfer events, such as carrier generation, trapping, detrapping, their surface, are discussed for each strategy hybrid ZnO. The synergistic effects mixed polymorphs theories proposed enhanced activity reported. highlights potential application different kinds pollutants from wastewater sources.
