Controlling the morphology of transition-metal nanoparticles (TMNPs) can be an effective way to produce nanomaterials with favourable properties (activity and selectivity, etc.). Here we reported the shape control syntheses of TMNPs including Ru, Rh, Pd, Os, Ir, Pt, alloy PtRu, PtOs, and PtRuOs by co-reducing their metal precursors and Ag(I) ions in an organic medium. In this approach, Ag(I) ions...
Controlling the size of Pt nanomaterials can be an effective route to improve their catalytic activity on a mass basis for the reactions of direct methanol fuel cell (DMFC). In this work we demonstrated the synthesis of ultrafine platinum nanoclusters based on the replacement reaction between Ag nanoparticles and Pt(IV) precursors. All the reactions were carried out in the presence of commercial carbon...
