Recent Progress on Ru-based Electrocatalysts for Hydrogen Evolution

摘要:

能源消耗持续增长以及化石燃料燃烧带来的能源安全与环保问题日益突出，开发安全、清洁、高效的新能源是人类可持续发展的重要课题。氢气具有能量密度高、无污染、资源丰富的优点，被视为最具发展潜力的石油与天然气的替代清洁能源。制氢最常用的方法是电解水，为实现高效制氢，通常需要添加催化剂（钌及钌基材料）提高析氢效果。本文详细介绍了铂（Pt）族元素中最便宜的金属元素钌（Ru）和钌基材料作为高效电催化剂的制备方法，阐明了析氢促进机理以及析氢效果，并提出了钌基析氢电催化剂的未来发展方向。

Abstract:

The continuous growth of energy consumption， and the energy security and environmental protection issues caused by the burning of fossil fuels have become increasingly significant. Therefore， the study of alternative energy sources has attracted widespread attention. Hydrogen has the advantages of high energy density， no pollution， and abundant resources. It is considered to be one of the most potential alternatives to oil and natural gas. The most common method of hydrogen production is electrolysis of water. To achieve efficient hydrogen production， it is usually necessary to add catalysts （ruthenium and ruthenium-based materials） to improve the hydrogen evolution effect. This article reviews the preparation methods of ruthenium （Ru）， the cheapest metal element among the platinum （Pt） group elements， and ruthenium-based materials as efficient electrocatalysts， and clarifies the hydrogen evolution promotion mechanism， hydrogen evolution effect， and stability.
