能源是经济社会发展的动力，对人类生存至关重要。催化反应是能源生产的关键环节，急需获得高活性、高选择性、高稳定性的催化剂。单原子催化剂（SACs）的出现为催化行业带来了一个新颖有效的发展方向，但由于高表面能和低金属负载量，单原子催化剂仍然存在一些不足。在SACs之前，颗粒催化剂被广泛研究，考虑到催化过程的复杂性，SACs与颗粒之间的协同效应以增强电催化性能成为一种流行的研究策略。优化结构配置带来的能级调节被证明可以改善电荷转移和分离行为。迄今为止，已经开发出各种类型的单原子和粒子催化剂（SA/PC），并将对两者之间相互作用的理解推向了更高的层次。然而，很少有关于系统地引入这种协同作用的报道。本文综述了SA/PCs的结构分类和作用机理，并介绍了电催化反应中协同催化剂的研究进展。此外，还讨论了此类催化剂的挑战和机遇。关于系统地引入这种协同作用的报道很少。本文综述了SA/PCs的结构分类和作用机理，并介绍了电催化反应中协同催化剂的研究进展。此外，还讨论了此类催化剂的挑战和机遇。关于系统地引入这种协同作用的报道很少。本文综述了SA/PCs的结构分类和作用机理，并介绍了电催化反应中协同催化剂的研究进展。此外，还讨论了此类催化剂的挑战和机遇。

Research progress on single atom and particle synergistic catalysts for electrocatalytic reactions

Energy is the driving force for economic and social development and is crucial for human survival. The catalytic reaction is a key part of energy production, so it is urgent to obtain catalysts with high activity, selectivity, and stability. The emergence of single-atom catalysts (SACs) brings a novel and effectual development direction to the catalysis industry, but there are still some deficiencies in SACs due to high surface energy and low metal loading. Before SACs, particle catalysts were widely studied, taking into account the complexity of the catalytic process, and the synergistic effect between SACs and particles to enhance the electrocatalytic performance has become a popular research strategy. The energy-level regulation brought about by the optimized structural configuration is shown to improve the charge transfer and separation behavior. To date, various types of single-atom and particle catalysts (SA/PCs) have been developed, and the understanding of the interaction between the two is pushed to a higher level. Nevertheless, there are few reports on the systematic introduction of this synergy. In this review, the structure classification and mechanism of SA/PCs are summarized, and the research progress on synergistic catalysts in electrocatalytic reactions is introduced. In addition, challenges and opportunities for such catalysts are discussed.
