摘　　要：A strategy of intensifying the visible light harvesting ability of anatase Ti02 hollow spheres(HSs)was developed,in which both sides of Ti02 HSs were utilised for stabilising Au nanoparticles(NPs)through the sacrificial templating method and convex surface-induced confinement.The composite structure of single Au NP yolk-Ti02 shell-Au NPs,denoted as Au@Au(Ti02,was rendered and confirmed by the transmission electron microscopy analysis.Au@Au(Ti02 showed enhanced photocatalytic activity in the degradation of methylene blue and phenol in aqueous phase under visible light surpassing that of other reference materials such as Au(Ti02 by 77%and Au@P25 by 52%,respectively,in phenol degradation. 关键词：Ti02 hollow spheres plasmonic Au nanoparticles CONFINEMENT visible light photocatalytic degradation
