PdCu alloy nanodendrites with tunable composition as highly active electrocatalysts for methanol oxidation

Abstract

PdCu alloy nanodendrites were prepared and exhibited enhanced catalytic properties towards methanol oxidation relative to commercial Pd/C.

Magnesium oxide supported bimetallic Pd/Cu nanoparticles as an efficient catalyst for Sonogashira reaction

“…SEM images of MgO@PdCu in different magnifications.EDS mapping images of the material MgO@PdCu was also studied(Figure 1, ESI).It can be seen that both Pd and Cu are mostly distributed evenly throughout each PdCu species, suggesting an alloy structure[111][112][113]. Furthermore, energy-dispersive X-ray spectroscopy (EDS) analysis of MgO@PdCu confirmed the presence of Pd, Cu, Mg and N species(Figure 2, ESI).In order to investigate the oxidation states of Pd and Cu in the solid support, X-ray photoelectron spectroscopy (XPS) of the MgO@PdCu was performed (Figure 5).…”

Palladium/Copper Nanoalloy Supported on Carbon Nanotubes for the Electrooxidation of Methanol and Ethylene Glycol

“…After alloying, the bifunctional mechanism/effect of Pd and Cu removes the reaction intermediates which are unavoidably produced that contains mainly CO ads . The presence of Cu in the alloy may quicken the oxidation of intermediates, and therefore, for the oxidation of intermediate CO, Cu is more dynamic compared to Pd …”

Facile Synthesis of PdCu Echinus‐Like Nanocrystals as Robust Electrocatalysts for Methanol Oxidation Reaction

“…As a simple and feasible strategy, introducing other metals to construct bimetallic alloy can cut the cost‐consumption simultaneously modify the electronic structure of Pd, in favor of promoting their electrocatalytic activity . Among multifarious bimetallic alloys reported previously, PdCu alloy have drawn considerable attention on account of the advantages of Cu such as sufficient reserves and low price . For instance, the bimetallic Pd 4 Cu 1 nanosheets alloy reported by Fan's group display higher electrocatalytic activity and resistance toward CO‐poisoning than monometallic Pd nanosheets.…”

[18,19] For instance, the bimetallic Pd 4 Cu 1 nanosheets alloy reported by Fan's group display highere lectrocatalytic activity and resistance towardC O-poisoning than monometallic Pd nanosheets. According to the DFT calculation and XPS analysis, the electronic structures of Pd were modulated by introducing Cu.…”
