使用简单、快速且廉价的方法合成纳米复合材料对于大规模生产和应用至关重要。微波加热已被认为是获得更高反应速率的有前途的方法；这种方法可以在短时间内完成新的反应。因此，通过微波辅助加热在几分钟内合成了碳负载的铂-铜纳米粒子（Pt-Cu NPs/C）。详细的电化学研究表明，Pt-Cu NPs/C 在乙醇氧化反应（EOR）和甲醇氧化反应（MOR）方面表现出比 Pt/C 更高的性能。经过1000次吹扫循环后，Pt3Cu NPs/C的EOR和MOR保留质量活性最高，表明催化剂具有良好的稳定性。在这项研究中，开发了一种通过快速微波加热提高纳米材料催化剂工业生产效率的新方法。
The use of simple, fast, and inexpensive methods to synthesize nanocomposites is essential for large-scale production and applications. Microwave heating has been recognized as a promising method to attain higher reaction rates; this approach allows to complete new reactions in a short period of time. Therefore, carbon-supported platinum–copper nanoparticles (Pt–Cu NPs/C) were synthesized by microwave-assisted heating within few minutes. Detailed electrochemical studies showed that Pt–Cu NPs/C exhibited higher performance for ethanol oxidation reaction (EOR) and methanol oxidation reaction (MOR) than Pt/C. After 1000 sweeping cycles, the highest retention mass activity of EOR and MOR of Pt3Cu NPs/C showed that catalysts had good stability. In this study, a new approach for boosting the efficiency of industrial production of nanomaterial catalysts by rapid microwave heating was developed.
