研究目的
Investigating the synthesis and application of ternary PtNiCu self-assembled nanocubes for plasmon-enhanced electrocatalytic hydrogen evolution and methanol oxidation reaction in visible light.
研究成果
The ternary PtNiCu alloy nanocubes exhibit superior catalytic performance for hydrogen evolution and methanol oxidation under visible light due to their regular morphology, more surface active sites, and the synergy between alloy effect and plasmon-induced photoelectric effect. This study paves the way for the rational design of ternary plasmonic electrocatalysts.
研究不足
The study focuses on the synthesis and application of ternary PtNiCu alloy nanocubes under visible light irradiation. The limitations include the specific conditions required for the synthesis and the focus on visible light-assisted reactions.
1：Experimental Design and Method Selection:
A one-pot high-temperature chemical reduction method was used to synthesize self-assembled ternary PtNiCu and binary PtCu alloy nanocubes. The growth mechanism of the alloy was investigated.
2：Sample Selection and Data Sources:
The samples were characterized using TEM, HRTEM, SEM, EDS, XRD, and XPS.
3：List of Experimental Equipment and Materials:
Hydrogen hexachloroplatinate hexahydrate, Copper (II) Chloride Dihydrate, nickel chloride hexahydrate, ethylene glycol, KI, and Polyvinylpyrrolidone were used.
4：Experimental Procedures and Operational Workflow:
The samples were prepared by adding precursors to ethylene glycol, followed by the addition of KI and PVP, and heat treatment at 160 °C for 1 hour. The products were washed by centrifugation.
5：Data Analysis Methods:
The electrochemical and photoelectrochemical tests were performed using a conventional CHI-660E electrochemical analyzer. The HER and MOR performance was evaluated in a three-electrode system.
