Particularly in metal materials, where surface reactions play a critical role, nanoarchitecture becomes the most influential factor affecting activity, selectivity, and stability. Focusing on platinum-group metals (PGMs) due to their inherently high efficiency in energy and environmental applications, this article provides a comprehensive review of synthetic methods for the morphological control of metal nanomaterials. The morphological control is classified into atomic arrangements in 0D, 1D, and 2D nanocrystals, as well as nanoporous structures, and the mechanisms of major reactions are covered in detail. Each chapter is supplemented with a table featuring several examples, facilitating the reader's understanding of the structural controls of PGMs. Finally, the article outlines future challenges in achieving novel metal nanoarchitecture. The hope is that this review provides valuable insights into the synthesis of PGM-based nanomaterials and serves as a guide for designing and synthesizing innovative metal nanostructures for diverse applications. In metal nanomaterials, the nanoporous structure and atomic arrangement play a crucial role in determining their properties. This review article provides an overview of different approaches to control the nanostructure of PGM-based nanomaterials. The approaches are categorized into two main topics: nanocrystals and mesoporous nanostructures. The synthesis methods and underlying mechanisms are discussed in detail, offering insights into the field.image English John Wiley & Sons Ltd.
