Enhanced Visible Light Active WO3 Thin Films Toward Air Purification: Effect of the Synthesis Conditions.

ABSTRACT: Taking our current environmental situation in the world into consideration, people should face growing problems of air and water pollution. Heterogeneous photocatalysis is a highly promising tool to improve both air and water quality through decomposition/mineralization of contaminants directly into harmless CO2 and H2O under ambient conditions. In this contribution, we focused on the synthesis of self-assembly WO3 thin films via an electrochemical approach in the aqueous electrolyte containing fluoride ions toward air purification. The effect of preparation conditions such as applied potential (10-50 V), anodization time (15-120 min), concentration of H2SO4 (0.5-1.5 M) and NaF (0.1-1.0 wt.%) on the morphology, photocurrent response, and photocatalytic activity addressed to removal of air
