Abstract

Mesoscopic structures of noble metal (NM) nanomaterials are important parameters that remarkably affect physicochemical properties and electrocatalytic performances. To date, various synthesis strategies have been proposed to prepare NM nanomaterials with well‐defined mesoscopic structures. Specifically, amphiphilic surfactants that chemically composed of hydrophobic tail(s) and hydrophilic head(s) have been utilized as functional templates to precisely engineer mesoscopic structures of NM nanomaterials and further optimize their electrochemical performance. Compared with traditional surfactants, dioctadecyldimethylammonium chloride (DODAC) is a functional amphiphilic surfactant that can assemble into vesical and cylinder micelles and thus template precise synthesis of NM nanomaterials with various advanced structures. In this review, recent developments in DODAC‐templated synthesis of high‐performance NM electrocatalysts with a specific focus on the findings in the group are presented. Three kinds of advanced NM mesoscopic structures, including one‐dimensional (1D) nanowires, three‐dimensional (3D) mesoporous nanospheres (MSs), and sophisticated hollow/asymmetric MSs, are described in detail. Meanwhile, the applications in various electrocatalytic reactions are presented to highlight high activity, selectivity, and stability of NM electrocatalysts. This review provides some insights into both synthesis and application exploration of high‐performance NM electrocatalysts by templated synthesis of amphiphilic surfactants.
