Abstract
Graphene-supported mesoporous titania nanosheets (G-TiO2) were synthesized successfully by employing liquid-phase exfoliated few-layers graphene as a template and sandwich-like graphene-silica as intermediates. The as-prepared G-TiO2 not only inherited the two-dimensional structure of directly exfoliated few-layers graphene, high specific surface areas and large aspect ratio, but also possessed a mesoporous structure with nano-sized crystalline titania being anchored on the graphene nanosheets. Such unique features could enhance significantly the photocatalytic activities of TiO2 for degradating of hazardous organic compounds such as methyl orange (MO), rhodamine B (RhB) and methylene blue (MB).
