Abstract: The research progress and applications of several kinds of noble metals such as gold, silver, platinum, palladium and rhodium as core or shell from the aspect of monometallic, bimetallic or multimetal core-shell system were summarized.The synthesis of silica core-shell structures were enjoying ever-increasing research interests for their important properties and diverse applications, such as catalytic, optics, diagnosis, photothermal therapy, and so forth.The development directions in the future were also pointed out.
