- Visible light-induced degradation of gas-phase acetaldehyde (CH3CHO) is investigated using O-deficient reduced TiO2-x-loaded carbon paper. The carbon paper is synthesized by the pyrolysis of a filter paper, and the reduced TiO2-x is prepared by the magnesiothermic reduction of commercial anatase TiO2. The surface areas of the non-carbonized filter paper and carbon papers obtained by carbonization at 400, 600, 800, and 1000 °C are 4.31 m2 g-1, 13.57 m2 g-1, 466.81 m2 g-1, 461.60 m2 g-1, and 26.28 m2 g-1, respectively. Although the as-prepared carbon papers possess much lower specific surface areas than that of commercial activated carbon (2200 m2 g-1), the carbon papers show better adsorption capabilities. The O-deficient reduced TiO2-x samples exhibit strong visible-light absorption, and the reduced TiO2-x-loaded carbon papers induce rapid degradation of CH3CHO and simultaneous generation of CO2 in both closed-circulation and continuous-flow modes under visible light irradiation (λ > 420 nm), attributed to the efficient adsorption of gas-phase CH3CHO by the carbon paper and the rapid and complete degradation of CH3CHO to CO2 by the active reduced TiO2-x. This strongly suggests that the reduced TiO2-x-loaded carbon paper is an efficient composite photocatalyst for the visible light-induced photocatalytic degradation of gas-phase CH3CHO. © 2017 The Royal Society of Chemistry.
