Rational Design of Bimetallic Au/Cu Nanostructure: An Efficient Catalyst for Methanol Oxidation

Abstract

We show the design of noble Au/Cu bimetallic nanostructures by a gentle solution process. Transmission electron microscopy (TEM), X‐ray diffraction (XRD), and X‐ray photoelectron spectroscopy (XPS) analysis confirm the presence of both Au and Cu in the Au/Cu bimetallic nanostructures. The Au/Cu catalyst was explored as an efficient electrocatalyst for methanol oxidation with a current density of 5.71 mA/cm2 at 0.46 V.

Interfacial Engineering of CuCo2S4/g-C3N4 Hybrid Nanorods for Efficient Oxygen Evolution Reaction

“…Development of methodologies for advancement of energy resources in sustainable fashion is highly attractive due to its ability to overcome negative outcomes brought about by the utilization of conventional fossil fuels. Consequently, an assortment of energy conversation strategies, for example, PEC water splitting, − electrocatalytic water splitting, − methanol oxidation, − N 2 reduction, − CO 2 reduction, − and rechargeable metal-air batteries, − have been paid increasingly more consideration inferable from their extraordinary potential for reducing the concern of energy needs. Among those, the electrocatalytic water oxidation reaction to produce oxygen can be regarded as a green and sustainable approach for generating alternative energy.…”

Au–Cu Bimetallic Nanostructures for Photothermal Antibacterial and Wound Healing Promotion

“…The obtained precipitates were placed in a vacuum drying oven for 36 h at 50 °C, and the vacuum degree was 0.09 MPa. The Au-CuNP powders were obtained . At the same time, we set up three groups of reactions with different ratios of raw materials (other reaction conditions are the same): (1) 0.03 g of chloroauric acid, 0.015 g of cupric chloride, 0.25 g of glucose, and 0.1 g of hexadecane; (2) 0.015 g of chloroauric acid, 0.03 g of cupric chloride, 0.25 g of glucose, and 0.1 g of hexadecane; (3) 0.03 g of chloroauric acid, 0.03 g of cupric chloride, 0.25 g of glucose, and 0.05 g of hexadecane.…”
