Graphitic carbon nitride materials have attracted significant interest in recent years and found applications diverse light-to-energy conversions such as artificial photosynthesis, CO2 reduction, or degradation of organic pollutants. However, their utilization synthetic photocatalysis, especially the direct functionalization C(sp3)–H bonds, remains underexplored. Herein, we report mesoporous gr...

In recent years, the increasing demand for clean and potable water has created a need efficient, cost-effective wastewater treatment. One of most promising methods is heterogeneous photocatalysis due to its ability mineralize organic molecules. This paper describes development flow-through packed bed reactor system based on column comprising glass beads coated with commercially available TiO2 (...

The photocatalytic activity of nanocomposites based on theta-modification aluminum oxide Al2O3 with different TiO2 content for heterogeneous photocatalysis and biodegradation pathogenic microorganisms under the action LED radiation a wavelength 405 nm has been studied. It was found that all investigated have activity. maximum antibacterial efficiency composites 8 wt% (reduction CFU Staphylococc...

Plasmonics has remained a prominent and growing field over the past several decades. The coupling of various chemical and photo phenomenon has sparked considerable interest in plasmon-mediated photocatalysis. Given plasmonic photocatalysis has only been developed for a relatively short period, considerable progress has been made in improving the absorption across the full solar spectrum and the...

This article used bentonite impregnated with titanium and silver, respectively, as photocatalyst, to degrade methylene blue (MB) under conditions of MB solutions exposed to sodium lamp and sunlight. Due to the semi-conducting properties of synthesized bentonite catalysts, when exposed to sodium lamp and sunlight, catalyst particles are excited for photocatalysis to achieve decolourization. Afte...

Molecular Modeling methods play a very important role in TiO₂ photocatalysis. Recent advances in TiO₂ photocatalysis have produced a number of interesting surface phenomena, reaction products, and various novel visible light active photocatalysts with improved properties. Quantum mechanical calculations appear promising as a means of describing the mechanisms and the product distributions of th...

Conventional photocatalysts are primarily stimulated using ultraviolet (UV) light to elicit reactive oxygen species and have wide applications in environmental and energy fields, including self-cleaning surfaces and sterilization. Because UV illumination is hazardous to humans, visible light-responsive photocatalysts (VLRPs) were discovered and are now applied to increase photocatalysis. Howeve...
