Abstract
Activated carbon (AC)-supported composites are emerging as a novel class of materials that hold great promise for environment-protecting applications. In this paper, we present an approach for the preparation of the AC–TiO2 composite with mold-pressing using pure anatase TiO2 and self-sinterable corn straw derivative as the carbon mesophase. In order to explore the effects of the carbon mesophase and some dopants on the phase transition of anatase to rutile TiO2, the samples were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). It was discovered that the transition could be validly influenced by the sort and content of the adulterants. As a result, the ratio between anatase and rutile could be controlled in order to improve the photocatalysis and sensing properties of TiO2. Therefore, a method for preparing the formed AC–TiO2 composite powders and monoliths with controllable anatase phase proportion for different applications could be established.
