Herein, an efficient nano TiO₂-functionalized graphene oxide nanocomposite photocatalyst was readily prepared, using an ordinary solvothermal technique. It was noted that the as-prepared nanocomposite yielded a quadruple degradation capacity of the previously reported P25-graphene composite photocatalyst towards methylene blue (MB). To elucidate this, the Brunauer–Emmett–Teller (BET)-specific surface area, conductivity, and water contact angle measurements were all carried out. It was found out that graphene oxide was endowed with nontrivial photocatalytic activity by increasing its content in the nanocomposite (from 1/100 to 1/9, with respect to the dosage of nano TiO₂). Overall, the nano TiO₂-functionalized graphene oxide nanocomposite is a promising candidate in applications of environment remediation.
