The noble-metal-based catalysts (NMBCs) have always been the promising catalytic materials in fuel cell electrocatalysis. Among diversified NMBCs, one dimension (1D) construction endows them with unique anisotropic structure, large specific surface area, and high flexibility and stability, which contribute to the superior catalytic behaviors than the bulk counterparts in fuel cell reactions, mainly including (anodic alcohol oxidation reaction (AOR) and cathodic oxygen reduction oxidation (ORR)). In the field of electrocatalysis, a large number of 1D NMBCs have been reported. However, a comprehensive review of the substructure design, as well as the systematic analysis of their performance enhancement still need further research and summary. In this review, we firstly expounded the basal understanding of AOR and ORR in fuel cells in terms of the catalytic mechanism and crucial problems, then discussed the recent advances and superiorities in the 1D NMBCs with well-defined substructures, involving 1D [email protected], ultrathin, networked, hollow, jagged, and heterogeneous structures. Moreover, we highlighted the advanced strategies for improving the catalytic performances of 1D NMBCs, which involves robust composition, interface, facet, strain, and defect engineering. Finally, we outlooked the challenges and perspectives for the further enhancement in precise synthesis, performance improvement, and mechanism investigation of 1D NMBCs towards fuel cell electrocatalysis.

用于高效燃料电池电催化的具有多种结构的一维贵金属基催化剂的最新进展

贵金属基催化剂(NMBCs)一直是燃料电池电催化中很有前途的催化材料。在多样化的 NMBCs 中,一维 (1D) 结构赋予它们独特的各向异性结构、大比表面积、高柔韧性和稳定性,这使得它们在燃料电池反应中的催化行为优于大块对应物,主要包括(阳极醇氧化反应(AOR)和阴极氧还原氧化(ORR))。在电催化领域,已经报道了大量的一维 NMBC。然而,对子结构设计的全面回顾,以及对其性能提升的系统分析,仍需进一步研究和总结。在本次审查中,我们首先从催化机理和关键问题的角度阐述了对燃料电池中 AOR 和 ORR 的基本理解,然后讨论了具有明确子结构的一维 NMBCs 的最新进展和优势,涉及一维 [电子邮件保护]、超薄、网络、中空、锯齿状和异质结构。此外,我们强调了提高一维 NMBC 催化性能的先进策略,包括稳健的成分、界面、刻面、应变和缺陷工程。最后,我们展望了进一步加强一维 NMBCs 对燃料电池电催化的精确合成、性能改进和机理研究的挑战和前景。然后讨论了具有明确子结构的一维 NMBC 的最新进展和优势,涉及一维 [电子邮件保护]、超薄、网络、中空、锯齿状和异构结构。此外,我们强调了提高一维 NMBC 催化性能的先进策略,包括稳健的成分、界面、刻面、应变和缺陷工程。最后,我们展望了进一步加强一维 NMBCs 对燃料电池电催化的精确合成、性能改进和机理研究的挑战和前景。然后讨论了具有明确子结构的一维 NMBC 的最新进展和优势,涉及一维 [电子邮件保护]、超薄、网络、中空、锯齿状和异构结构。此外,我们强调了提高一维 NMBC 催化性能的先进策略,包括稳健的成分、界面、刻面、应变和缺陷工程。最后,我们展望了进一步加强一维 NMBCs 对燃料电池电催化的精确合成、性能改进和机理研究的挑战和前景。应变和缺陷工程。最后,我们展望了进一步加强一维 NMBCs 对燃料电池电催化的精确合成、性能改进和机理研究的挑战和前景。应变和缺陷工程。最后,我们展望了进一步加强一维 NMBCs 对燃料电池电催化的精确合成、性能改进和机理研究的挑战和前景。
