Abstract
The destruction of acetaldehyde (CH 3CHO) photo-catalytically beneath Vis light irradiation using Cu doped TiO 2 (8 × 10 −2 mol%), Co-doped TiO 2 (8 × 10 −2 mol%) and Cu, Co co-doped TiO 2 (8 × 10 −2 mol%) nanoparticles have been investigated. The results reveal that Cu doped TiO 2 (8 × 10 −2 mol%), Co-doped TiO 2 (8 × 10 −2 mol%) and Cu, Co codoped TiO 2 (8 × 10 −2 mol%) nanoparticles are efficient photo-catalysts for the destruction of CH 3CHO using Vis light illumination. Co, Cu-codoped TiO 2 specimen displayed the biggest speed value of carbon dioxide gas evolution, achieving 990 ppm of carbon dioxide gas at the end of 300 min of Vis light illumination, that was 1.1, 1.3 and 99 much greater than that of Co-doped TiO 2, Cu-doped TiO, and titania, respectively. Due to doping of metal enhance photocatalytic activity by enhancing generated electron–hole pairs or retard the re-consolidation speed of electrons and holes. The major products from photo-catalytic destruction of acetaldehyde are H 2O and CO 2. Therefore, 0.08 mol% Co, Cu co-doped TiO 2 photo-catalyst is regarded as safe photo-catalyst for complete degrade of acetaldehyde under visible light from indoor atmospheric environments without produce toxic by-products.
