▎ 摘　　要

A series of B-doped graphene (BG)/rod-shaped TiO2 (RT) nanocomposites were firstly synthesized via a facile one-step hydrothermal reaction in NaBH4 aqueous solution. The photocatalytic activity of the obtained nanocomposites for the oxidative photo-destruction of NOX gas was investigated, and they showed better photocatalytic properties than pure TiO2 and graphene/TiO2 nanocomposites. This work could provide new insight into the fabrication of TiO2-carbon nanocomposites as high performance photocatalysts and facilitates their application in addressing environmental protection issues.
