Preparation and Photocatalytic Properties of CQDs-Modified 26-Facet Cu/Cu2O Composites

Bi/BiOI/carbon quantum dots nano-sheets with superior photocatalysis

“…Nowadays, energy shortage and environmental pollution are the two key issues facing the world. [1][2][3][4][5][6][7] Since photocatalysis by semiconductors has been regarded as one of the most efficient ways to resolve water pollution and energy issues, semiconductors emerge in large numbers. 1,4,[8][9][10][11][12] Recently, BiOX (X = Cl, Br, I) attracts a lot of attention due to its outstanding performance.…”

Green Synthesis of ZnO and Black TiO2 Materials and Their Application in Photodegradation of Organic Pollutants

“…First, it may use renewable and sustainable solar energy sources to power photoreactions, making it a promising, green, and economically feasible approach. Second, since its only by-products are water and carbon dioxide, it does not cause any secondary pollution. − The type of photocatalyst, however, largely determines how well photocatalysis functions to degrade organic pollutants. ZnO and TiO 2 have drawn the most attention among photocatalysts and are thought to be the most effective.…”

“…When compared to pure rutile TiO 2 , H 2 O 2 -modified black TiO 2 demonstrated 3-fold greater photocatalytic performance for organic dye degradation. Sun et al 201 used a hydrogenation process with NaBH 4 as an H 2 source to prepare black TiO 2 with improved NIR and visible-light absorption. Naldoni et al 18 have shed light on the specific structural and electronic characteristics of these catalytic materials, as well as the fundamental structure–activity correlations that govern the formation of crystal defects, enhanced light absorption, charge separation, and photocatalytic activity.…”
