从单金属、双金属或多金属的SiO2核壳体系出发,论述了几种典型的贵金属金、银、铂、钯、铑等为核或壳与SiO2包覆的核壳纳米材料的制备方法,改进的性质和在催化、光学、生物等方面的应用,并对未来的发展方向进行了展望.
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.
