Synthesis of titanium dioxide–reduced graphite oxide nanocomposites and their photocatalytic performance

Chemically bonded titanium dioxide (TiO 2 )–reduced graphite oxide (RGO) composites have been successfully prepared with graphite oxide and peroxotitanium complex by low‐temperature liquid reaction. The prepared TiO 2 nanoparticles with diameters of about 10 nm consisted of anatase phase and a slight amount of brookite phase. In the TiO 2 –RGO composites, TiO 2 nanoparticles were uniformly dispersed on the RGO surface from the scanning electron microscopy images. The as‐prepared TiO 2 –RGO composites exhibited much higher efficiency in the degradation of methylene blue under ultraviolet light irradiation compared with pure TiO 2 nanoparticles. In addition, the influences of the RGO content in the TiO 2 –RGO composites on the photocatalytic degradation activity were also researched.
