Publication date: Available online 28 March 2019Source: Nano TodayAuthor(s): Junjie Mao, Jun Li, Jiajing Pei, Yan Liu, Dingsheng Wang, Yadong LiAbstractControlling the structure of noble-metal-based nanomaterials (NMNs) with precision at an atomic level has received considerable attention in recent years. However, the complexity of synthetic process poses great challenges in the delicate design and fine control of NMNs. In this review, we focus on recent progress made in the chemical synthesis of NMNs at an atomic level, which include surface engineering of NMNs, atomic layer coating of NMNs, metal doping or substitution, and intermetallic compounds. The catalytic properties of well-controlled NMNs are discussed. Finally, the major challenges and opportunities pertaining to the controllable synthesis of NMNs are presented. We believe this brief review provides up-to-date information on the fine tuning of NMNs structures, and offers some new perspectives of this rapidly developing field.Graphical abstract
