Abstract
Abstract Electrochemical energy conversion devices, with typical examples of fuel cells, are the centers in building a sustainable energy system that avoids environmental pollution and lowers the dependence on fossil fuels. Platinum (Pt)‐based catalysts are among the most potential candidates to drive these reactions due to their superior catalytic performance. Among the various Pt‐based catalysts, Pt‐based ultrathin nanowires exhibit remarkable catalytic performance due to the unique structural merits ( i.e ., high Pt atom utilization and strong interaction with supports). In this review, we attempt to summarize the recent advances in the synthesis of Pt‐based ultrathin nanowires, as well as their applications in various kinds of electrocatalytic reactions. We conclude this review with an emphasis on the current challenges in terms of synthesis and applications of Pt‐based ultrathin nanowires. Perspectives on further development are also proposed, which is expected to guide the related research in the future.
