Photocatalytic activity enhancement of TiO₂ with adding Zn particles

Abstract

APhotocatalysis process uses ambient oxygen from air and irradiation, fundamentally UV light, to generate oxidation and reduction which can degrade almost all harmful organic and inorganic compounds to nontoxic substances. This study was focused on enhancement of photocatalytic activity which improves the photocatlytic efficiency with TiO 2 particle by mixing of certain amounts of Zn particles. We analyzed degradation of organic pollutant materials such as toluene and phenol with the mixed photocatalysis by using UV-visible spectrophotometer and obtained a result that photocatalytic activity is increased with increasing amount of Zn particle. Especially, in the case of TiO 2 (1 mmol) and Zn (0.1 mmol) mixture photocatalyst, we obtained at least 2 times higher photocatalytic activity compared with the commercially available TiO 2 photocatalyst (Degussa P-25), indicating that our mixed photocatalyts (Zn-doped TiO 2 ) is very effective of removing both organic dye and pollutants and the conversion rate of toluene is much faster than that of phenol.

Photocatalytic CO2 Reduction and Thermal CO Oxidation to CO2 over Cu/Ni-loaded TiO2 Photo and Thermal Catalysts

“…Titanium dioxide (TiO 2 ) has been widely used as a model catalyst material in various areas such as photo and thermal catalytic applications for energy and environment [1][2][3][4][5][6]. To satisfy increasing demand, considerable effort has been devoted to the designing of new catalysts with higher catalytic performance [1,[7][8][9].…”
