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 PtCu 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.
使用简单、快速且廉价的方法来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一种有前景的实现更高反应速率的方法；这种方法能够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载铂 - 铜纳米颗粒（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）中表现出比Pt/C更高的性能。经过1000次扫描循环后，PtCu NPs/C的EOR和MOR的最高保留质量活性表明催化剂具有良好的稳定性。在本研究中，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。
