Abstract

Hydrogen spillover effect has recently garnered a lot of attention in the field of electrocatalytic hydrogen evolution reactions. A new avenue for understanding the dynamic behavior of atomic migration in which hydrogen atoms moving on a catalyst surface was opened up by the setup of the word “hydrogen spillover.” However, there is currently a dearth of thorough knowledge regarding the hydrogen spillover effect. Currently, the advancement of sophisticated characterization procedures offers progressively useful information to enhance our grasp of the hydrogen spillover effect. The understanding of material fabrication for hydrogen spillover effect has erupted. Considering these factors, we made an effort to review most of the articles published on the hydrogen spillover effect and carefully analyzed the aspect of material fabrication. All of our attention has been directed toward the molecular pathway that leads to improve hydrogen evolution reactions performance. In addition, we have attempted to elucidate the spillover paths through the utilization of DFT calculations. Furthermore, we provide some preliminary research suggestions and highlight the opportunities and obstacles that are still to be confronted in this study area.

电催化中的氢溢出效应:探索原子迁移的奥秘
氢溢出效应最近在电催化氢气进化反应领域引起了广泛关注。氢溢出 "一词的出现为理解氢原子在催化剂表面移动的原子迁移动态行为开辟了一条新途径。然而,目前人们对氢溢出效应还缺乏全面的了解。目前,先进的表征程序为我们提供了越来越多的有用信息,有助于我们更好地掌握氢溢出效应。对氢溢出效应材料制造的了解也在不断深入。考虑到这些因素,我们努力回顾了已发表的大部分有关氢溢出效应的文章,并仔细分析了材料制造方面的问题。我们的注意力全部集中在提高氢气进化反应性能的分子途径上。此外,我们还尝试利用 DFT 计算来阐明溢出路径。此外,我们还提供了一些初步研究建议,并强调了该研究领域仍需面对的机遇和障碍。

期刊介绍: Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. The journal aims to publish high quality research related to materials for energy harvesting, conversion, storage, and transport, as well as for creating a cleaner environment. EEM welcomes research work of significant general interest that has a high impact on society-relevant technological advances. The scope of the journal is intentionally broad, recognizing the complexity of issues and challenges related to energy and environmental materials. Therefore, interdisciplinary work across basic science and engineering disciplines is particularly encouraged. The areas covered by the journal include, but are not limited to, materials and composites for photovoltaics and photoelectrochemistry, bioprocessing, batteries, fuel cells, supercapacitors, clean air, and devices with multifunctionality. The readership of the journal includes chemical, physical, biological, materials, and environmental scientists and engineers from academia, industry, and policy-making.
