Recent Advances in the Synthesis and Electrocatalytic Applications of Platinum‐Based Bimetallic Alloy Nanostructures

Abstract

Pt‐based bimetallic alloy nanomaterials with a low Pt loading can exhibit promising catalytic properties with exciting electrochemical applications. An effective structure control of Pt‐based bimetallic alloy nanomaterials is critical to achieve enhanced catalytic properties. This review article focuses on recent advances in the controllable synthesis and electrocatalytic applications of Pt‐based bimetallic alloy nanostructures. Recent contributions on the controllable synthesis of a rich variety of Pt‐based bimetallic alloy nanostructures, for example, PtPd, PtCu, PtNi, PtCo, and PtFe, and hybrid nanostructures based on Pt‐based bimetallic alloy nanomaterials are summarized. Different Pt‐based bimetallic alloy nano‐electrocatalysts with enhanced activity and durability for different electrocatalytic reactions, such as the fuel cell reaction and the hydrogen evolution reaction, are outlined. Finally, an outlook on future trends and developments is provided.

Atomic Layer Deposition of Ni on Cu Nanoparticles for Methanol Synthesis from CO2 Hydrogenation

“…Bimetallic nanoparticles have been extensively studied owing to their enhanced chemical, mechanical, electrical, and geometric properties with respect to those of their monometallic counterparts . Because of these particular features, bimetallic nanoparticles have drawn much attention in catalytic applications including the fuel cell reaction, higher alcohol synthesis, as well as methanol synthesis . Among all the bimetallic nanoparticles, CuNi alloys have shown superior performance for methanol synthesis than other bimetals such as AuCu, PdCu, and PtCu .…”

Platinum single-atom adsorption on graphene: a density functional theory study

“…1,2 Nevertheless, there is still an urgent need to address the high cost of Pt and to search for alternative catalysts, which use small amounts of Pt or no Pt with earth-abundant materials. Tremendous efforts have been devoted to achieve these goals, including the use of non-precious metals for Pt-metal alloys, [3][4][5][6][7][8][9] or the use of noble metal-free catalysts. [10][11][12][13] Particularly interesting are Pt clusters supported by graphitic materials, such as carbon black, carbon nanotubes, and graphene, which have been extensively studied both experimentally, [14][15][16][17][18][19][20] and theoretically.…”

Study of PtPd Bimetallic Nanoparticles for Fuel Cell Applications

“…Among Pt-based catalysts, Pt-Pd is one of the most attractive bimetallic systems due to its application as electrocatalyst in fuel cells [13][14][15] and various applications including hydrogenation [16][17] and oxidation of organic compounds 18 . Several studies have been carried out about the synthesis and electrocatalytic properties of the Pt-Pd bimetallic NPs [19][20][21][22] ; these bimetallic NPs can be produced generally , and spectroscopy data can be obtained either simultaneously or sequentially from the same region of the specimen 25 . Also, STEM has the potential to achieve atomic resolution images in three dimensions using electron tomography 26 .…”
