The role of interfacial effects on enhanced catalytic performance of TiO2-graphene nanocomposites

ORAL

Abstract

Graphene-containining TiO2 nanocomposites have significantly higher photocatalytic activity compared to bare TiO2 films. The enhancement is result of improved transport and higher efficiency of the charge carries separation at carbon-TiO2 interface. These effects were assessed by comparison of six anatase-graphene structures, fabricated by different synthesizing techniques and referenced to the performance of TiO2--graphitic-carbon and TiO2--Au thin films.
