Abstract：

TiO　2　hollow　spheres　modified　with　spatially　separated　Ag　species　and　RuO　2　cocatalysts　have　been　prepared　via　an　alkoxide　hydrolysis–precipitation　method　and　a　facile　impregnation　method.　High-resolution　transmission　electron　microscopy　studies　indicate　that　Ag　species　and　RuO　2　co-located　on　the　inner　and　outer　surface　of　TiO　2　hollow　spheres,　respectively.　The　resultant　catalysts　show　significantly　enhanced　activity　in　photocatalytic　hydrogen　production　under　simulated　sunlight　attributed　to　spatially　separated　Ag　species　and　RuO　2　cocatalysts　on　TiO　2　hollow　spheres,　which　results　in　the　efficient　separation　and　transportation　of　photogenerated　charge　carriers.　©　2017　by　the　authors;　licensee　MDPI,　Basel,　Switzerland.
