Abstract

Abstract

A novel Bi₂WO₆/SC photo-catalyst was synthesized by hydrothermal method with semi-coke (SC) as the support. The as-prepared catalyst was characterized by SEM, BET, XRD, FT-IR and UV-vis diffuse reflectance spectra; its photo-catalytic activity in NO oxidation under visible light irradiation (λ> 400 nm) was evaluated. The results indicate that Bi₂WO₆ obtained by hydrothermal method displays micro-flower structure and absorption spectrum toward the visible light region above 400 nm. The Bi₂WO₆/SC catalyst exhibits excellent photo-catalytic activity in NO removal; NO conversion remains higher than 70% after reaction under irradiation for 4 h.
