Abstract

Abstract : Carbon‐modified TiO2 composite was synthesised via the template method and multi‐step calcinations by using a tinfoil package. The carbon‐coated TiO2 (C–TiO2 ) composite was characterised via X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy and N2 sorption and thermogravimetry. TiO2 was wrapped up in a carbon layer with a thickness of less than 1 nm. The specific surface area and pore volume of C–TiO2 were 95.6 m 2 g −1 and 0.247 cm 3 g −1, respectively. The C–TiO2 composite exhibited mesopore structures, showed preferable adsorption capacity for methyl orange and had a higher photocatalytic activity than its unmodified counterpart.
