Characterization and catalytic properties of nano-sized Ag metal catalyst on TiO2–SiO2 synthesized by photo-assisted deposition and impregnation methods

Zeolite Y from rice husk ash encapsulated with Ag-TiO2: characterization and applications for photocatalytic degradation catalysts

“…The fine TiO 2 powder, or crystals, can be dispersed in the water, in order to be clarified by irradiation; however, they must be removed by filtering after reaction, which is troublesome and costly. Thus, in order to solve this problem, many researchers have examined methods of fixing TiO 2 on other supporting materials, including glass beads [20][21][22], fiberglass [23][24][25], silica [26,27], an electrode [28], and zeolite [29,30]. Recently, some researchers have used zeolite as hosts to fix semiconductors, due to its unique, uniform pores and channel size.…”

Fast fabrication of Co3O4 and CuO/BiVO4 composite photocatalysts with high crystallinity and enhanced photocatalytic activity via ultrasound irradiation

“…Nowadays, photocatalysis based on the utilization of solar energy has attracted much attention due to its promising applications in environmental treatments [1][2][3][4][5][6][7][8][9]. Among the photocatalysts, TiO 2 has received the most attention as a photocatalytic material because of its chemical and physical durability, high activity, nontoxicity, and low cost [10,11].…”

Composition and phase control of Ni/NiO nanoparticles for photocatalytic degradation of EDTA

“…Most of previous reports devoted to remove EDTA from water using heterogeneous catalysis have been conducted using TiO 2 semiconductor catalyst irradiated with wide range of spectral lamps [15][16][17][18][19][20][21]. This means, to date there are challenges for developing the controlling parameters of the heterogeneous photocatalysis, including developing new types of catalyst, deep investigation on catalyst operation and its performance evaluation and other relevant aspects as well.…”
