采用选择性溶解法制备了具有多孔结构的Pt20Si80合金。采用单辊熔旋法制备了具有纳米PtSi化合物三维网络结构的Pt20Si80带状先驱体合金。然后通过电化学选择性溶解去除Si基体，从而获得3D纳米多孔PtSi化合物。预计这种多孔PtSi化合物将在电催化剂、光电子器件以及红外探测器领域得到应用。该研究为从多相体系中挖掘三维网络相来制备多孔化合物或合金开辟了一条新的途径。
PtSi compound with porous structure had been synthesized by selective dissolution of a pre-prepared Pt20Si80alloy. A Pt20Si80ribbon precursor alloy with the structure of nano-scale PtSi compound 3D network embedded in Si matrix was pre-prepared using a single-roller melting-spinning method. Then the Si matrix is removed by electrochemical selective dissolution and thus the 3D nanoporous PtSi compound is obtained. It is expected that this porous PtSi compound will find applications in the field of electrocatalyst, optoelectronic devices, as well as infrared detectors. This study paves a new way for the fabrication of porous compounds or alloys by excavation of a 3d network phase from a multiphase system.
