利用可再生能源产生的电能电解水制取氢气,被认为是下一代清洁能源的最佳选择之一。然而,通过电解水可持续的产生氢气需要高活性的催化剂来使得反应有效地进行。基于类石墨烯二维材料的析氢反应电催化剂展现出巨大的潜力,因而备受关注。本文主要结合我们课题组近期在析氢反应电催化剂方面的研究,介绍了类石墨烯二维材料的析氢反应电催化剂的研究进展,主要包括过渡金属二硫族化合物、前过渡金属碳化物(MXenes)以及硼单层纳米片等。最后总结和展望了析氢反应电催化剂所面临的挑战与未来发展方向。
Hydrogen produced from electrochemical water-splitting driven by renewable resource-derived electricity is considered a promising candidate for clean energy. However, sustainable hydrogen production from water splitting requires highly active catalysts to make the process efficient. Catalysts based on graphene-like lwo-dimensional (2D) materials present great potential in the hydrogen evolution reaction (HER) and thus gain attention. In this review, which is a combination of our recent works, we highlight research efforts towards electrocatalysts for the HER based on 2D materials including transition metal disulfides, MXenes, and boron monolayers. Finally, we summarize the challenges and prospects for future development of electrocatalysts for the hydrogen evolution reaction.
