Abstract

ZnO/4-mercaptobenzoic acid (4-MBA)/Au composite particles have been prepared by interconnecting the flower-like ZnO particles and Au nanoparticles with functional molecules 4-MBA. SEM measurements have shown that the obtained composite particles have very homogeneous shape and size. The surface coverage of Au nanoparticles on ZnO/4-MBA particles can be tuned by changing the molar ratio of ZnO/4-MBA to Au. The Raman spectra of ZnO/4-MBA and ZnO/4-MBA/Au particles indicate the presence of the interaction between ZnO, Au particles and 4-MBA molecules.
