Porous Pt–M (M = Cu, Zn, Ni) nanoparticles as robust nanocatalysts

Abstract

Porous Pt-M (M = Cu, Zn, Ni) nanoparticles (NPs) were obtained by reduction of [Pt(CH3NH2)4][PtCl4] and M(Ac)2 (or MCl2) with oleylamine under mild conditions. The porous Pt-Cu NPs exhibited superior catalytic activities over a Pt/Cu NP mixture and Cu NPs as references for CO oxidation processes.

RhCu 3D Nanoframe as a Highly Active Electrocatalyst for Oxygen Evolution Reaction under Alkaline Condition

“…A great improvement in this area has been feasible with facet‐controlled nanoparticles and core–shell nanoparticles with lattice mismatch, which enables surface‐energy modulations . Most notably, phenomenal enhancement in catalytic performance has been accomplished by framework nanostructures with dramatically increased surface area per volume, and a great deal of current interest resides on the design and synthesis of novel nanoframework structures . Pt‐based alloy nanoframeworks constitute a majority of nanoframeworks and the application of these nanostructures is mostly confined to the fuel cell electrode oxygen reduction reaction (ORR) .…”

“…除了上述所提到的结构外, 用共还原法可以合成 已被报道的绝大部分的合金结构. 本课题组 [30] 在油胺 中还原金属前驱体得到了笼状多孔Pt-Cu和树枝状多 孔Pt-Zn、Pt-Ni纳米颗粒, 并通过一步溶剂热法合成了 具有纳米空心球(NHSs)、纳米线(NWs)和纳米四面体 (NTs)结构的Ir-Pd合金 [31] . 将溶剂热法与化学刻蚀法相 结合, 得到Rh-Cu、Rh-Ni、Rh-Pd-Cu八面体纳米框 架 [32] 和PtRuCu菱形十二面体纳米框架 [33] 结构.…”

Facile synthesis of ternary PtPdCu alloy hexapods as highly efficient electrocatalysts for methanol oxidation

“…Of them, introducing a second metal (e.g., Pd, Cu, Ru and Ni) alloyed with Pt is the one of the most widely used method. [16][17][18][19][20][21] The enhancement in the catalytic properties for MOR can be understood by bifunctional mechanism and/or ligand effect through improving the tolerance of Pt toward CO poisoning. 22 For example, Sun and co-workers reported the synthesis of single-crystalline dendritic Pt 3 Cu nanocubes with the mass activity being 5.2 times higher than that of commercial Pt/C for MOR.…”
