Abstract
Remarkable progress has characterized the field of electrocatalysis in recent decades, driven in part by an enhanced comprehension of catalyst structures and mechanisms at the nanoscale. Atomically precise metal nanoclusters, serving as exemplary models, significantly expand the range of accessible structures through diverse cores and ligands, creating an exceptional platform for the investigation of catalytic reactions. Notably, ligand-protected Au nanoclusters (NCs) with precisely defined core numbers offer a distinct advantage in elucidating the correlation between their specific structures and the reaction mechanisms in electrocatalysis. The strategic modulation of the fine microstructures of Au NCs presents crucial opportunities for tailoring their electrocatalytic performance across various reactions. This review delves into the profound structural effects of Au NC cores and ligands in electrocatalysis, elucidating their underlying mechanisms. A detailed exploration of the fundamentals of Au NCs, considering core and ligand structures, follows. Subsequently, the interaction between the core and ligand structures of Au NCs and their impact on electrocatalytic performance in diverse reactions are examined. Concluding the discourse, challenges and personal prospects are presented to guide the rational design of efficient electrocatalysts and advance electrocatalytic reactions.
近几十年来,电催化领域取得了显著进展,部分原因是对纳米级催化剂结构和机理的理解得到了提高。原子级精密金属纳米簇作为典范,通过不同的核心和配体大大扩展了可访问结构的范围,为研究催化反应创造了一个卓越的平台。值得注意的是,配体保护的金纳米簇(NC)具有精确定义的核数,在阐明其特定结构与电催化反应机制之间的相关性方面具有明显优势。对金纳米团簇的微观结构进行战略性调控,为定制其在各种反应中的电催化性能提供了重要机会。本综述深入探讨了 Au NC 内核和配体在电催化中的深远结构影响,并阐明了其潜在机制。接下来将详细探讨 Au NC 的基本原理,包括核心和配体结构。随后,研究了 Au NCs 内核和配体结构之间的相互作用及其对各种反应中电催化性能的影响。最后,提出了面临的挑战和个人展望,以指导高效电催化剂的合理设计和推进电催化反应。
