TiO2/carbon composite (TiO2/HTC), synthesized by hydrothermal
carbonization, was characterized by thermogravimetric analysis, nitrogen
adsorption–desorption isotherms and X-ray diffraction. The possibility of
using TiO2/HTC as photocatalysts for UV and visible light assisted
degradation of methylene blue in aqueous solution was examined. It was
found that carbon presence in TiO2/HTC leads to the higher porosity and
increase in the share of photocatalytically active anatase phase. Compared to
the hydrothermally synthesized TiO2, TiO2/HTC showed the superior
photocatalytic activity under UV irradiation. In addition, TiO2/HTC show
high recycling ability with degradation ratio of methylene blue higher than
81 % after five cycles. Also, TiO2/HTC is expected to be a promising
candidate for photocatalytic processes using visible light.
