▎ 摘　　要

Little attention has been paid to synthesis and application of TiO2 nanobelt/grapheme composites (TiO2/GR). In this work, a facile one-pot solvothermal approach to synthesize TiO2/GR was developed. In such processes, the reduction of graphene oxide (GO) nanosheets was accompanied by generation of TiO2/GR in one-step. In vitro experiments revealed that the renal cancer (RENCA) cell viability decreased sharply to 4.72% in the presence of the resulting composites in the near infrared light (NIR) window.
