由于材料设计、合成控制和反应表征方面的进步，三金属纳米颗粒的开发和应用继续迅速加速。随着多组分材料在汽车尾气和光伏方面的技术成功，现在可以通过精心制备多元素颗粒来实现协同效应，这在催化领域提供了令人兴奋的机会。在这篇综述中，我们从实验和计算两方面探讨了目前在三金属纳米催化剂的设计、合成、分析和应用方面所使用的方法，并为新兴的三金属纳米催化剂领域提供了一个关键的视角。三金属纳米颗粒通常被支撑在高表面积的金属氧化物上，用于催化应用，其合成条件与单金属和双金属纳米颗粒的制备条件相当。然而，由于系统的异质性，控制元素分离和随后的表征仍然具有挑战性。多元素组成在重要的氧化、脱氢和加氢反应中表现出有益的协同作用；在某些情况下，这是通过更高的选择性来实现的，同时也观察到活性的改善。然而，在确定和利用有影响的特征以实现最大生产力方面仍然存在挑战。计算为实验努力提供支持，例如在电催化方面，并且明确需要将模拟结合起来，考虑到组合元素筛选和最佳反应设计，以实验最大化这一新兴领域的生产力。在有效地识别、制造和应用三金属催化剂方面，仍然存在明显的挑战，但基础现在是可见的，这个令人兴奋的化学领域的前景是强大的。
The development and application of trimetallic nanoparticles continues to accelerate rapidly as a result of advances in materials design, synthetic control, and reaction characterization. Following the technological successes of multicomponent materials in automotive exhausts and photovoltaics, synergistic effects are now accessible through the careful preparation of multielement particles, presenting exciting opportunities in the field of catalysis. In this review, we explore the methods currently used in the design, synthesis, analysis, and application of trimetallic nanoparticles across both the experimental and computational realms and provide a critical perspective on the emergent field of trimetallic nanocatalysts. Trimetallic nanoparticles are typically supported on high-surface-area metal oxides for catalytic applications, synthesized via preparative conditions that are comparable to those applied for mono- and bimetallic nanoparticles. However, controlled elemental segregation and subsequent characterization remain challenging because of the heterogeneous nature of the systems. The multielement composition exhibits beneficial synergy for important oxidation, dehydrogenation, and hydrogenation reactions; in some cases, this is realized through higher selectivity, while activity improvements are also observed. However, challenges related to identifying and harnessing influential characteristics for maximum productivity remain. Computation provides support for the experimental endeavors, for example in electrocatalysis, and a clear need is identified for the marriage of simulation, with respect to both combinatorial element screening and optimal reaction design, to experiment in order to maximize productivity from this nascent field. Clear challenges remain with respect to identifying, making, and applying trimetallic catalysts efficiently, but the foundations are now visible, and the outlook is strong for this exciting chemical field.
