Abstract
Metal-support interaction is vital of modulating electronic structure of metal nanoclusters as well as stabilizing these nanoclusters. In this study, a series of Ru-based catalysts supported on CNT doped with diverse nonmetallic elements, including O, N, and S (denoted as Ru/x-CNT), are delicately designed to investigate the relationship of metal-support interaction and HER activities. Compared with N-CNT and S-CNT, O-CNT-supported Ru NCs manifest the stronger metal-support interactions due to its high charge transfer between Ru and substrate, which exhibits a remarkable low overpotential of 10 mV at 10 mA cm−2 and excellent stability at 100 mA cm−2. This work confirms that enhanced metal-support interactions are benefited to improve both HER activity and stability.
金属-支撑相互作用对调节金属纳米团簇的电子结构和稳定金属纳米团簇至关重要。在本研究中，我们精心设计了一系列钌基催化剂，在掺杂不同非金属元素（包括O、N和S）的碳纳米管上负载钌基催化剂（表示为Ru/x-碳纳米管），以研究金属-载体相互作用与HER活性的关系。与N-CNT和S-CNT相比，o - cnt负载的Ru NCs由于其在Ru和衬底之间的高电荷转移而表现出更强的金属-载体相互作用，在10 mA cm - 2下表现出10 mV的过电位，在100 mA cm - 2下表现出优异的稳定性。这项工作证实，增强金属支持相互作用有利于提高HER活性和稳定性。图形抽象
