Effects of catalyst characters on the photocatalytic activity and process of NiO nanoparticles in the degradation of methylene blue

Facile synthesis of silver nanoparticles and their application in dye degradation

“…The size dependent reactivity and large surface area have made them efficient catalysts [12]. Several researchers have reported the use of nanocatalysts for the effective removal of dye stuffs [12][13][14][15].…”

The enhanced photocatalytic activity of Zn2+ doped TiO2 for hydrogen generation under artificial sunlight irradiation prepared by sol–gel method

“…Ever since Fujishima and Honda reported TiO 2 photochemical electrode for splitting water in 1972 [6], the study on the development of photocatalysts used for the hydrogen production and the utilization of solar energy has attracted increasing attention [7,8]. The reported photocatalyst systems, to the best of our knowledge, can be generally classified as oxides (TiO 2 , ZnO, NiO) [9][10][11], sulfides (CdS, ZnS) [12,13], and halides (AgCl, AgBr) [14,15]. However, among these semiconductors, TiO 2 is considered as an excellent photocatalyst for hydrogen production due to its nontoxicity, stability, low price and resistance to chemicals and photochemical corrosion [16][17][18][19].…”

Synthesis and characterization of zinc oxide/maghemite nanocomposites: Influence of heat treatment on photocatalytic degradation of 2,4-dichlorophenoxyacetic acid

“…This process is a superior method for wastewater treatment due to its ability to mineralize a wide range of recalcitrant contaminants by generating highly reactive hydroxyl radicals [2][3][4][5]. In the field of photocatalysis, semiconductor photocatalysis has received increasing attention due to its inherent destructive nature, which can lead to complete mineralization of organic carbon or herbicide organic compounds to carbon dioxide and water [6][7][8][9]. In addition, this advanced process can be carried out under ambient conditions using atmospheric oxygen as the oxidant [10].…”
