Abstract
With the rapid development of renewable energy utilization, hydrogen production by electrochemical water hydrolysis has attracted renewed research interest. The improvement of unit mass activity of low-Pt loading catalysts for hydrogen evolution reaction (HER) and the reduction of cost is attractive and challenging. Herein, the sulfide of the VIB subgroup metal (M = Cr, Mo, W) was prepared by a simple and mild electroreduction method, and Pt nanoparticles were grown on the sulphide of the VIB subgroup by Pulse electrodeposition. The M-Pt-S composite catalysts show excellent HER activity. Especially, Mo-Pt-S shows excellent HER performance (η10 = 30.12 mV) in 0.5 M H2SO4 and excellent unit mass activity of 26.63 A mg−1 at 50 mV, which is superior to the corresponding monofunctional Pt noble metal catalyst.
期刊介绍：
The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied.
Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
