Low bias photoelectrocatalytic (PEC) performance for organic vapour degradation using TiO2/WO3 nanocomposite

▶ A novel PEC flat-plate type device suitable for the gas-phase application is supplied. ▶ TiO2/WO3 composite needs much lower bias than TiO2 for the activity enhancement. ▶ The absorption wavelength range of the TiO2/WO3 composite, compared with WO3, is redshifted. ▶ The explanation based on the transportation of the electrons is proposed.
