摘要:

电解水作为一种绿色制氢技术备受关注,设计开发适用于全pH(pH=0~14)介质的高效、低廉的电催化剂,可实现减少能耗、简化装置构建和优化生产工艺。二硫化钼具有电子结构的可调性以及除贵金属外最合适的热力学活性,是极具前景的析氢材料之一。通过综述二硫化钼基全pH析氢材料的研究现状,涉及本征二硫化钼物性调节策略以及原子掺杂的表面工程和界面工程调制,阐明了相应的催化增强机制,揭示了制备全pH范围兼具活性和高电流稳定性的催化剂是电催化材料的发展趋势,并提出激活多级结构二硫化钼材料惰性基面、提高材料整体导电性、精准锚定单原子以及包覆多孔碳是设计高效全pH催化剂的根本策略。

Abstract:

As a green hydrogen production technology, electrolyzed water splitting has received lots of attention.Design and development of high-efficient and low-cost electrocatalysts,which are suitable for full pH(pH=0-14) media,can reduce ener-gy consumption,simplify device construction and optimize production process.MoS2 has been considered as one of the pro-mising materials for electrochemical hydrogen evolution,due to its tunable electronic structure and the most suitable thermo-dynamic activity except for precious metals.The current research progress of MoS2-based pH-universal catalysts for electro-chemical hydrogen evolution reaction was reviewed,such as modulating physical property of intrinsic MoS2,surface engineer-ing with atom doping,and interface engineering.The corresponding catalytic mechanism was clarified.It was revealed that preparation of catalysts with both hydrogen evolution activity and stability at high current density in all-pH range would be the tendency of electrocatalytic materials.It was also proposed that activation of inert basal plane for multi-level structural MoS2 materials,enhancement of the whole electroconductivity,anchor of single atoms precisely,and encapsulation of active materials with porous carbon would be the fundamental strategies for designing efficient pH-universal catalysts.

Key words: MoS2, pH-universal, electrocatalytic hydrogen evolution, electrolysis of water
