Facile electrodeposition fabrication of molybdenum-tungsten sulfide on carbon cloth for electrocatalytic hydrogen evolution

摘要

In this work, we have described a facile fabrication of molybdenum-tungsten sulfide on carbon cloth (Mo-W-S/CC) by one-step electrodeposition process. The morphology, composition and catalytic property of as-prepared samples have been characterized through scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photo-electron spectroscopy (XPS) and electrochemical methods. The electrodeposition conditions have been optimized systematically. Mo-W-S/CC has achieved excellent performance and durability as an electrocatalyst for hydrogen evolution reaction (HER) in acidic electrolytes. (C) 2017 Hydrogen Energy Publications LLC.
