Catalysts play a pivotal role in modern industries, such as energy, pharmaceuticals, and petrochemicals, serving as cornerstone of high-tech production. Noble metals, such as gold, silver, and platinum group elements, possess the superb catalytic characteristics of high-temperature oxidation resistance, corrosion resistance, stable electrochemical performance, high catalytic activity, and so on. These characteristics offer excellent prospects for applications in catalysis. In this review, we summarize innovative approaches to regulating the size and morphology of nano-noble metal catalysts with different dimensions. We also showcase typical prominent examples of their applications in exhaust gas purification, battery manufacturing, water splitting, and selective hydrogenation. Finally, perspectives are discussed in terms of future research opportunities in the realm of noble metal nanocatalysts.

“…Metal nanowires also have the advantages of inherent anisotropic structure and high flexibility. [ 182–184 ] Common metal nanowires include Ag nanowires, Ni nanowires, Cu nanowires, and Ti nanowires, all of which show great potential for carrier applications. Lang et al drop cast silver nanowires onto polydimethylsiloxane and subsequently electrodeposited Pd to generate flexible Pd/AgNWs/polydimethylsiloxane electrodes.…”

Direct methanol fuel cell (DMFC) can be used as a promising portable power device due to its excellent energy conversion efficiency and low pollutant emissions. The performance of DMFC largely depends on the anode electrocatalyst for methanol oxidation reaction (MOR). As an important part of the electrocatalyst, the carrier greatly affects the activity and stability of the electrocatalyst. Herein, the research progress of carbonaceous carriers (such as activated carbon, nanostructured carbon), noncarbonaceous carriers (metal compounds), and conducting polymers in DMFC is reviewed. Furthermore, an overview of the development of self‐supporting carriers for flexible DMFC electronics is presented. Its role as the most ideal DMFC carrier in the future provides new ideas for the challenges and development of the commercialization of flexible DMFC.

“…The electrochemical oxidation reactions of small organic molecules play an important role in the development of environmentally-friendly and economic fuel cells, which can efficiently convert chemical energy into electric energy and enable next-generation transport tools. [193][194][195] The aforementioned small organic molecules, such as methanol, ethanol, and formic acid, possess high energy density and facile on-board storage. Typically, H 2 O and CO 2 are the main nal products of the small organic molecule oxidation reactions, in which a 2electron transfer, 6-electron transfer, and 12-electron transfer occur for the formic acid oxidation reaction (FAOR), 196 methanol oxidation reaction (MOR), 197 and ethanol oxidation reaction (EOR), 198 respectively.…”
