The pivotal role of size and morphology-controlled nanocrystals in catalysis is a recognized fact nowadays. Among the strategies developed to adjust such features, colloidal synthetic approaches have been proven to be a valuable alternative through which noble metal nanocrystals with tailored sizes and morphologies can be formed upon proper selection of the experimental conditions. This review summarizes some of the main aspects to be considered in the synthesis of colloidal noble metal and includes representative examples of their catalytic applications by spotlighting the experimental conditions used in the synthesis and how the size and/or shape of the nanocrystals influence in the final catalytic performance.

尺寸和形态控制的纳米晶体在催化中的关键作用是当今公认的事实。在发达国家，调整这些特征的策略，胶态的合成方法已被证明是通过其具有定制的尺寸和形态的贵金属纳米晶体可根据实验条件适当选择来形成一种有价值的替代。这篇综述总结了胶体贵金属合成中应考虑的一些主要方面，并通过重点介绍合成中使用的实验条件以及纳米晶体的尺寸和/或形状如何影响最终合成，介绍了其催化应用的代表性实例。催化性能。
