The development of doped noble metal catalysts with nonmetal elements to improve the catalytic performance toward the oxygen reduction reaction (ORR) is significant for proton exchange membrane fuel cell technology. Here, we report a one-pot for dual-nonmetal-doping strategy for the synthesis of S and P-co-doped mesoporous PtPd nanocages (PtPdSP mNCs) by using pre-synthesized mesoporous PtPd nanocages (PtPd mNCs) as the precursor and triphenylphosphine sulphide as both S and P sources. Benefitting from the combined advantages of metal–nonmetal incorporation, hollow cavity and surface porosity, the resultant quaternary PtPdSP mNCs exhibit outstanding ORR activity and long-term stability. This research work provides a good strategy for the doping of two or more selected nonmetallic elements into metallic nanocrystals with a controllable structure and composition.

将二元非金属S和P共掺杂到中孔PtPd纳米笼中可促进氧还原电催化作用。

对于质子交换膜燃料电池技术而言，开发具有非金属元素的掺杂贵金属催化剂以改善对氧还原反应（ORR）的催化性能具有重要意义。在这里，我们报告一个罐，通过使用预先合成的介孔PtPd纳米笼（PtPd mNCs）作为前体和三苯基膦来合成S和P-共掺杂的介孔PtPd纳米笼（PtPdSP mNCs）的双非金属掺杂策略硫化物既可作为硫源也可作为磷源。得益于金属-非金属结合，中空空腔和表面孔隙率的综合优势，所得的四元PtPdSP mNCs具有出色的ORR活性和长期稳定性。
