Cu-doped mesoporous TiO2 photocatalyst for efficient degradation of organic dye via visible light photocatalysis

Green Organo-Photooxidative Method for the Degradation of Methylene Blue Dye

“…The public, particularly entrepreneurs, are concerned about conditions that negatively impact the environment, , such as industrialization and urbanization that have affected the quality of water supplies . Chemical contamination, especially wastewater generated by the textile industries, contains a significant amount of colors and toxic synthetic mixtures that are responsible for environmental toxicity and have affected the clarity and taste of water, making it unpleasant to consumers. , Water is one of the most valued assets on earth, but it contains a lot of pollutants, including metal ions, anions, phenol, dyes, detergents, and pesticides . Textile dyeing uses a dye pigment to color the products, and the dye causes problems with light penetration into water and interference with photosynthesis as well as with human beings. , In addition to being toxic and carcinogenic, some dyes pose a serious environmental and human health risk .…”

Laser processing of Li-doped mesoporous TiO2 for ambient-processed mesoscopic perovskite solar cells

“…25,26 However, to our knowledge, there have been no reported studies on the utilisation of laser treatment for the fabrication of metal-doped m-TiO 2 . In addition, due to the large surface area and tunable porosity, metal-doped m-TiO 2 has been widely used in the field of photocatalytic water splitting, 27 degradation of pollutants and organic dyes, 28 energy storage, 29 biosensing, 30 antibacterial applications. 31 Therefore, developing a rapid and scalable method to process metal-doped m-TiO 2 will potentially contribute not only to the perovskite community but also to a broader audience in the related fields engaged with using metal-doped m-TiO 2 .…”

Ag Nanoparticles Supported on h-BN/BiPO4 Heterostructures as a Photocatalyst for the Degradation of Rhodamine B

“…The photocatalytic capacity of a material is dependent on its redox ability. In other words, the photocatalyst with a wide band gap meets the following conditions: the conduction band (CB) is lower than the reduction potential of water (−0.046 eV) and the valence band (VB) is higher than the oxidation potential of water (2.38 eV), normally demonstrating strong redox ability and high degradation capacity. − As a commonly seen wide band gap photocatalyst, titanium dioxide (TiO 2 ) ( E g > 3.0 eV for both rutile and anatase TiO 2 ) proved to be capable of organic pollutant degradation under irradiation with ultraviolet (UV) light. − Nevertheless, due to the low solar energy utilization and high carrier recombination rate, its application in photocatalytic degradation is limited. Accordingly, excavating photocatalysts with a broad light adsorption spectrum and a low electron–hole recombination − is a topic that needs continuous exploration.…”
