Electrocatalysts play a significant performance in renewable energy conversion, supporting several sustainable methods for future technologies. Because of the successful fabrication of distinctive oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) electrocatalysts, bifunctional ORR/OER and HER/OER electrocatalysts have become a hot area of contemporary research. ORR, OER, and HER have gained considerable attention because of their strong performance in different energy conversion and storage devices, including water-splitting devices, fuel cells, and metal–air rechargeable batteries. Therefore, the development of effective nanostructured multifunctional electrocatalysts for ORR, OER, and HER is necessary; and there is a demand for their industrialization for sustainable energy technology. In this review, details of current improvements in multifunctional catalysts for ORR/OER as well as HER/OER are presented, focusing on insight into the theoretical considerations of these reactions through investigation and estimation of different multifunctional catalysts. By analyzing the universal principles for various electrochemical reactions, we report a systematic scheme to clarify the recent trends in catalyzing these reactions over various types of nanostructure catalysts. The relevant reaction pathways and the related activity details for these reactions in the current literature are also included. Overall, the current demands and future outlines for improving the prospects of multifunctional electrocatalysts are discussed.

用于高效能量转换系统的纳米结构多功能电催化剂:最新观点

电催化剂在可再生能源转化中发挥着重要作用,为未来的技术提供了几种可持续的方法。由于成功制备了独特的氧还原反应(ORR),氧释放反应(OER)和氢释放反应(HER)电催化剂,双功能ORR / OER和HER / OER电催化剂已成为当代研究的热点。由于ORR,OER和HER在不同的能量转换和存储设备(包括水分解设备,燃料电池和金属空气可充电电池)中具有出色的性能,因此备受关注。因此,有必要开发用于ORR,OER和HER的有效的纳米结构多功能电催化剂。并且它们需要工业化以实现可持续能源技术。在这篇综述中,介绍了ORR / OER和HER / OER多功能催化剂当前改进的详细信息,重点是通过研究和评估不同的多功能催化剂,深入了解这些反应的理论考虑。通过分析各种电化学反应的通用原理,我们报告了系统的方案,以阐明在各种类型的纳米结构催化剂上催化这些反应的最新趋势。当前文献中还包括这些反应的相关反应途径和相关活性细节。总体上,讨论了改善多功能电催化剂前景的当前需求和未来纲要。通过研究和评估不同的多功能催化剂,重点研究这些反应的理论考虑。通过分析各种电化学反应的通用原理,我们报告了系统的方案,以阐明在各种类型的纳米结构催化剂上催化这些反应的最新趋势。当前文献中还包括这些反应的相关反应途径和相关活性细节。总体上,讨论了改善多功能电催化剂前景的当前需求和未来纲要。通过研究和评估不同的多功能催化剂,重点研究这些反应的理论考虑。通过分析各种电化学反应的通用原理,我们报告了系统的方案,以阐明在各种类型的纳米结构催化剂上催化这些反应的最新趋势。当前文献中还包括这些反应的相关反应途径和相关活性细节。总体上,讨论了改善多功能电催化剂前景的当前需求和未来纲要。我们报告了一个系统的方案,以阐明在各种类型的纳米结构催化剂上催化这些反应的最新趋势。当前文献中还包括这些反应的相关反应途径和相关活性细节。总体上,讨论了改善多功能电催化剂前景的当前需求和未来纲要。我们报告了一个系统的方案,以阐明在各种类型的纳米结构催化剂上催化这些反应的最新趋势。当前文献中还包括这些反应的相关反应途径和相关活性细节。总体上,讨论了改善多功能电催化剂前景的当前需求和未来纲要。
