Adsorption and Photocatalytic Kinetics of Visible-Light Response N-Doped TiO2 Nanocatalyst for Indoor Acetaldehyde Removal under Dark and Light Conditions

Figure 2

Adsorption and photooxidation of acetaldehyde onto the N-TiO2 in the absence of light (dark) and under visible-light irradiation (light). Experimental conditions: [CH3CHO] = 176–1010 ppmv and temperature = 25°C.
