▎ 摘　　要

We reported the fabrication of highly porous graphene/TiO2 composite nanofibers in the form of a nonwoven mat by electrospinning followed by calcination in air at 450 degrees C. The graphene can uniformly disperse in highly porous TiO2 nanofibers. The highly porous graphene/TiO2 composite nanofibers exhibited excellent catalytic activities. The new method for producing graphene/TiO2 composite nanofibers is versatile and can be extended to fabricate various types of metal oxide and graphene nanocomposites.
