Influence of Calcination Temperature on the Structure and Visible Light Photocatalysis Performance of Mn–TiO2-Loaded Wooden Activated Carbon Fibers

Binqing Sun, Yin Chen, Xiaojun Ma


Mn–TiO2-loaded wooden activated carbon fibers (Mn/TiO2-WACF) were prepared through sol–gel and impregnation methods and characterized by X-ray diffractometer, scanning electron microscope, Fourier transform IR spectrometer, and automatic adsorption apparatus to observe the influence of load calcination temperature on its morphological structure and visible light photocatalysis performance. Results showed that Mn doping elevated the phase transformation temperature (650 °C–750 °C) of TiO2 in Mn/TiO2-WACF; the particle size of anatase TiO2 in the sample gradually enlarged with the increase of calcination temperature. The N2 adsorbing quantity of Mn/TiO2-WACF sample initially increased and then decreased as calcination temperature increased, and 650 °C became the turning point of its N2 adsorbing quantity. The degradation methylene blue solution for Mn/TiO2-WACF sample under visible light gradually decreased with the increase of calcination temperature, and the methylene blue solution degradation by the sample obtained under 450 °C calcination temperature reached 93%.
