Abstract：

Graphene-pasted　TiO2　spheres　have　been　prepared　successfully　by　a　two-step　method　including　attaching　relatively　small　graphene　oxide　sheets　onto　the　surface　of　the　modified　TiO2　spheres　and　in-situ　photocatalysis　reduction　of　these　graphene　oxide　sheets.　Since　coated　almost　totally　on　the　surface　of　TiO2　spheres,　these　added　graphene　sheets　are　utilized　more　fully　in　these　as-obtained　graphene-pasted　composites,　which　possess　more　interfaces　between　graphene　and　TiO2　and　can　make　better　use　of　the　irradiated　light　compared　with　that　of　traditional　graphene-involved　TiO2　composites.　As　a　result,　these　graphene-pasted　TiO2　spheres　always　display　higher　photocatalysis　activity　in　both　methylene　orange　dye　degradation　and　4-nitrophenol　reduction　than　that　of　control　graphene-TiO2　spheres　in　the　case　of　the　same　usage　of　these　carbon　sheets,　which　indicates　more　efficient　use　of　graphene　sheets　in　these　graphene-pasted　samples　in　photocatalysis　systems.　©　2015　Elsevier　Ltd.
