复合固溶体（CSS）纳米粒子是近年来发现的一种高效的电催化剂。作为许多优点之一，它们表现出用过渡金属的多元组合替代贵金属催化剂的潜力，因为它们提供了彼此相邻的多个元素的新的独特和可定制的活性位点的形成。该观点报告了当前状态和多元纳米颗粒的（组合）合成的挑战以及用于在原子尺度上揭示结构-活性相关性的先进电子显微镜表征技术。我们讨论了这种材料与普通催化剂的区别，以突出其作为电催化剂的潜力，并使其非典型的电化学行为合理化。我们提供了一个概述的挑战，在合成，表征和电化学评价，并提出指导方针，为未来的CSS催化剂的设计，以实现在这一研究领域，这仍然处于起步阶段的进一步进展。
Complex solid solution (CSS) nanoparticles were recently discovered as efficient electrocatalysts for a variety of reactions. As one of many advantages, they exhibit the potential to replace noble-metal catalysts with multinary combinations of transition metals because they offer formation of new unique and tailorable active sites of multiple elements located next to each other. This Perspective reports on the current state and on challenges of the (combinatorial) synthesis of multinary nanoparticles and advanced electron microscopy characterization techniques for revealing structure-activity correlations on an atomic scale. We discuss what distinguishes this material class from common catalysts to highlight their potential to act as electrocatalysts and rationalize their nontypical electrochemical behavior. We provide an overview about challenges in synthesis, characterization, and electrochemical evaluation and propose guidelines for future design of CSS catalysts to achieve further progress in this research field, which is still in its infancy.
