中国化学:英文版 2015年第1期33卷 119-124页

作者： yi cui ding zhou Zhuyin Sui baohang han national center for nanoscience and technology Beijing 100190China University of Chinese Academy of Sciences Beijing 100049China

Graphene oxide(GO)-wrapped gold nanoparticles(Au NPs)hybrid materials are constructed via one-pot sono-chemical synthesis and self-assembly,using ethylene glycol as the reducing *** synthesis process above took only 1 h,and the obtained hybrid materials exist as spheres wrapped with gauze-like GO sheets via ionic in-teraction-based *** GO sheets are helpful for the well dispersion of the Au ***,these materials possess enhanced photocatalytic activity under visible light irradiation,owing to the synergistic effect of the two components in the hybrid *** work may provide a convenient approach to control the size and morphology of the Au NPs for the synthesis of GO-wrapped hybrid materials,which opens up a feasible way to synthesize metal NPs/GO ***,this method might lead to developing of a broad class of new functionalized materials wrapped with GO sheets.
