摘要: 详细研究了交替微波加热法制备多壁碳纳米管负载Pt 催化剂(Pt/MWCNTs)的过程中交替微波加热(5s-on/5s-off)次数对催化剂性能的影响. X射线粉末衍射(XRD)结果表明, Pt 的晶粒尺寸在开始的加热阶段基本上没有发生变化，但是随着加热次数的增多, Pt 的晶粒尺寸逐步增大. 采用循环伏安法和旋转圆盘电极技术考察了催化剂的电化学活性. 结果显示, 以5s-on/5s-off 加热20 次时, 催化剂显示出最佳的催化活性; 在0.5mol·L^-1 H₂SO₄饱和氧水溶液中催化剂的氧还原起峰电位接近1.0 V (vs RHE). 交替微波加热法简单经济, 在大批量制备催化剂等纳米材料方面显示出较好的应用前景.

Abstract: The influence of intermittent microwave heating (IMH) on the physicochemical and electrochemical properties of platinum loaded on multi-walled carbon nanotubes (Pt/MWCNTs) was investigated. X-ray diffraction results revealed that the crystal size of Pt particles hardly increased for smaller numbers of pulse repetitions, but became much larger as the number of pulse repetitions increased. Cyclic voltammetry (CV) and rotating disk electrode (RDE) results showed that the Pt/MWCNTs catalysts prepared by IMH in a repeated pulse form of 5s-on/5s-off for 20 pulse repetitions possessed the largest electrochemical surface area. An onset potential of approximately 1.0 V (vs RHE) was observed for the oxygen reduction reaction in oxygen-saturated 0.5 mol·L^-1 H₂SO₄ aqueous solutions. The IMH method is simple, economical, and can potentially be scaled up for the mass production of nanomaterials.
