Research on Ru Nanoparticles Loaded on B, N Co-Doping Carbon Support for Electrocatalytic Hydrogen Evolution Performance
摘要: 金属–载体相互作用不仅调控金属的电子结构，还可以稳定金属纳米颗粒，被认为是一种提高电解水析氢反应性能的有效策略。本文采用4,4’-联吡啶与Cs2[closo-B12H12]为前驱体，通过静电组装制备了新型硼有机聚合物(BOPs)，并以此作为还原剂和载体，原位还原–煅烧两步法制备硼氮双掺杂碳载体负载钌纳米颗粒催化剂(Ru/BCN)。主要探究了合成过程中不同煅烧温度对于Ru/BCN的HER性能的影响，研究发现Ru/BCN-700展现出最佳的析氢活性，在碱性介质中仅需要17 mV的过电位就可达到10 mA cm−2的电流密度，并且具有良好的稳定性和耐久性。
Abstract: Metal-carrier interaction not only regulates the electronic structure of metals but also stabilizes metal nanoparticles, which is considered an effective strategy for improving the performance of electrolytic water hydrogen evolution reaction. In this paper, a novel boron organic polymer (BOPs) was prepared by electrostatic assembly using 4,4’-bipyridine and Cs2[closo-B12H12] as precursors, and BOPs was used as the reducing agent and carrier. The in situ reduction-calcination two-step method was employed to prepare ruthenium nanoparticle catalyst supported on boron-nitrogen double-doped carbon carrier (Ru/BCN). The influence of different calcination temperatures on HER properties of Ru/BCN during the synthesis process was primarily investigated. It was found that Ru/BCN-700 exhibited the best hydrogen evolution activity with a current density of 10 mA cm−2 achieved at only 17 mV over potential in alkaline medium, demonstrating good stability and durability.
