This article proposes a general approach for the preparation of intermetallic nanoparticles of PtSn, PtSn, PtSn, and PtSn, triggered by hexamethyldisilazane (HMDS) in conjunction with SnCl. The ethanol oxidation reaction (EOR) tests demonstrate the improved specific activity of PtSn intermetallic nanoparticles (PtSn), due to the lower binding energy between carbon monoxide (CO) and PtSn, the oxidation state of Sn, and the presence of Pt-Sn bonds on the surface. Strikingly, PtSn with an optimized Pt : Sn ratio of 1 : 1 holds superior EOR performance and stability to other PtSn intermetallics. In addition, PtSn intermetallic nanoparticles including PtSn, PtSn, and even the most Sn-rich PtSn hold a higher specific current density than the commercial Pt/C after a long-term test, showing the enhanced stability for the EOR. Furthermore, this method was also successfully extended to the synthesis of other Sn-containing intermetallic nanoparticles, such as AgSn and CuSn
