Abstract

Hydrogen, which can be readily produced by electrochemical water splitting, has been hailed as one of the most promising green energy sources. In a water electrolyzer, catalysts are needed for the hydrogen evolution reaction (HER) at the cathode, which are traditionally based on platinum-based materials. Recently, carbon-based nanocomposites have emerged as viable alternatives, which are mostly prepared by pyrolysis or wet chemistry methods, which are time- and energy-consuming. We have exploited magnetic induction heating (MIH) for ultrafast and green preparation of high-performance HER electrocatalysts. A novel MIH method was developed for the ultrafast and green preparation of carbon-supported Ru NPs toward HER in alkaline media, where the size and morphology of the Ru NPs can be readily manipulated by the heating current and duration. It is expected that MIH can be exploited for the design and engineering of high-performance nanocomposite catalysts for important electrochemical energy technologies.
磁感应加热制备金属/碳纳米复合电催化剂的高效析氢反应
氢是一种极具发展前景的绿色能源,它可以通过电化学水分解制备。在水电解槽中,阴极的析氢反应(HER)需要催化剂,传统的催化剂是基于铂基材料。近年来,碳基纳米复合材料已成为一种可行的替代方法,但碳基纳米复合材料大多采用热解或湿化学方法制备,耗时且耗能大。我们利用磁感应加热(MIH)超快、绿色制备高性能HER电催化剂。研究了一种在碱性介质中制备碳负载钌纳米粒子的超快速和绿色制备方法,该方法可以通过加热电流和加热时间来控制钌纳米粒子的大小和形态。可望将MIH用于重要的电化学能源技术的高性能纳米复合催化剂的设计和工程。
