Morphology controlled bulk synthesis of disc-shaped WO3 powder and evaluation of its photocatalytic activity for the degradation of phenols

The effect of sunlight induced surface defects on the photocatalytic activity of nanosized CeO2 for the degradation of phenol and its derivatives

“…In some available studies, Bi 2 O 3 , WO 3 and V 2 O 5 [12][13][14][15] has established their candidacy as suitable sunlight active photocatalysts therefore, in this study, we evaluated the photocatalytic activity of pure CeO 2 in sunlight exposure for the degradation of stable phenolic substrates.…”

Semiconducting Materials

“…cubic (Mi et al 2012). WO 3 has also been considered to be a photocatalytic material, because of its high stability in aqueous solution under acidic condition, non-photocorrosion, and a proper band gap for visible light absorption (2.4-2.8 eV) which makes it a suitable candidate for the photocatalytic degradation of organic pollutants under solar irradiation (Aslam et al 2014;Hong et al 2009 (Kim et al 2010). The inability of O 2 to scavenge CB electrons in WO 3 makes it less favorable to separate the photogenerated electrons from the hole, and thus WO 3 alone is not an efficient photocatalyst.…”

Construction of novel ternary component photocatalyst Sr0.25H1.5Ta2O6·H2O coupled with g-C3N4 and Ag toward efficient visible light photocatalytic activity for environmental remediation

“…Till now, many attempts have been developed to overcome these shortcomings for developing superior visible light photocatalysts, including metal or non-metal doping [8,9], morphology control [10,11], heterojunction [12,13] and so forth. In particular, construction of a semiconductor heterojunction has garnered great research attention because of its perfect effectiveness in improving the photocatalytic activity.…”
