摘要
氢能作为一种清洁能源,已成为全球能源战略的重要组成部分,也是实现全球“碳中和”的必要途径之一.在可再生电力的驱动下,水电解法有望成为实现“零碳”排放的一种理想的长期制氢方法.与传统合金相比,高熵合金由于其独特的结构特征,包括占位无序和晶格有序,可提供更多的催化活性位点.它们在水解催化剂领域具有广泛的应用前景.本文综述了电解水的机理、水解过程中高熵合金的催化原理,以及高熵合金作为电解水催化剂的最新研究进展.总结了新型高熵合金设计方面存在的难点及其应用潜力,重点讨论了高熵合金在水解催化过程中表面形态和催化活性之间的联系.最后归纳了高熵合金的组成调控及其在水电解等新兴领域的可能应用前景.
As a clean energy carrier,hydrogen energy has become part of the global clean energy strategy and one of the necessary routes to achieve global carbon neutrality.Driven by renewable electricity,water electrolysis promises to be an ideal long-term hydrogen production method that can realize net zero carbon emissions.Compared with conventional alloys,high-entropy alloys(HEAs)have much more catalytic active sites due to their unique structural features including occupation disorder and lattice ordering.They have various promising applications in the field of hydrolysis catalysts.Herein,in this review,the mechanisms of electrolysis of water,catalytic principles of HEAs in hydrolysis processes and latest research progress of HEAs as water electrolysis catalysts are summarized.We also provide perspectives on the difficulties and potential linked to novel HEA design approaches in this attractive sector,with a focus on the connection between both the surface morphology and the catalysis activity.The compositions and possible applications of HEAs in water electrolysis and other emerging fields are outlined.
