A study on Mn doped ZnO loaded on CSAC for the photocatalytic degradation of brilliant green dye

Highly efficient visible light active Cu–ZnO/S-g-C3N4 nanocomposites for efficient photocatalytic degradation of organic pollutants

“…Then, these electrons from the CB of SGN are shifted to the CB of ZnO, owing to the lower CB edge potential (−0.5 eV) of ZnO than CB potential (−1.12 eV) of g-C 3 N 4 . 71–74 The doped Cu atoms in the CZS-25 NC at the SGN and ZnO interfaces function as mediators to transfer electrons from SGN to ZnO, and decrease the recombination frequency of electrons and holes. The electrons at the CB of ZnO are consumed in the induction of superoxide radicals (O 2 − ) by reacting with chemisorbed O 2 on the surface of CZS-25 NC.…”

Synthesis of Co‐doped Cu2O Particles and Evaluation of their Photocatalytic Activity in the Degradation of Norfloxacin

“…Among them, it has become a research hotspot to produce defects in Cu 2 O crystals by doping with metal ions to improve its efficiency. Nithya et al [13] prepared Mn-doped Cu 2 O particles by chemical precipitation method, which has a larger specific surface area and better catalytic performance. Cao et al [14] prepared Mn-doped BiOCl particles to increase the specific surface area, expands its light absorption area and promote photo-induced carriers to improve its degradation efficiency.…”

Controllable growth of Cu–Bi co-doped ZnO nanospheres on cotton fabrics and a study on their photocatalytic performance in visible light

“…Most prepared ZnO had mainly one-dimensional and twodimensional morphologies in the current literature, and the multidimensional morphology of ZnO was seldom reported; [17][18][19] moreover, ZnO only reacts in the ultraviolet region due to its nature, so researchers adopted doping modication to expand its application in visible light. [20][21][22] Nithya et al 23 introduced Mn doped nano-sized ZnO, which was prepared by a chemical precipitation method, and the results showed that the band gap of Mn doped ZnO was obviously reduced, and the degradation of BG dye solution reached 97.47% under solar light, which showed outstanding photocatalytic performance. Wang et al 24 reported the ower-like ZnO doped with Ce and the results showed that the photocatalytic effect under solar irradiation was 80.56% higher than that of pure ZnO.…”
