摘要
氢气是一种丰富、可再生的清洁燃料,电解水需要高效稳定的催化剂来实现低过电位析氢。目前,Pt是最好的析氢催化剂,但价格昂贵导致其无法大规模使用推广。基于地球上蕴藏丰富元素如铁、钴、镍、钼、钨等制备新型材料并将其用于电化学析氢领域已受到广泛关注,但开发具有高活性及稳定性的新型催化剂仍然是一个很大的挑战。因此,我们将采用程序控温还原及化学气相沉积等技术制备具有新型结构的催化剂,对其进行系列表征后将其作为高效电催化剂用于析氢研究。与已报告的大多数非贵金属催化剂相比,该催化剂展示出优异的析氢性能。我们相信该类工作将为开发设计低价、稳定和高效电极材料并用于水电解及相关领域开辟新途径。
Hydrogen is considered as a clean and renewable energy alternative to fossil fuels. Water electrolysis requires an active, stable and cheap electrocatalyst for hydrogen evolution reaction(HER) to achieve low overpotential and fast kinetics for practical applications. Although Pt-based catalysts show high catalytic performance, they suffer from high cost and the scarcity of Pt. Extensive attention has been paid to fabricate earth-abundant elements-based materials and apply them for electrochemical HER, but developing high-performance HER catalysts is still a big challenge. Therefore, we employ temperature-programmed reduction and chemical vapor deposition techniques to prepare novel catalyst, perform serial characterizations and apply them as highly efficient electrocatalysts for HER. Compared to the most of the reported noble metal-free catalysts, our catalyst exhibits excellent hydrogen evolution performance. These works would open up exciting new avenues to design and develop other nanostructures as cheap, robust, and efficient electrode materials toward HER and other applications.
