The ever‐increasing need for the production and expenditure of sustainable energy is a result of the astonishing rate of consumption of fossil fuels and the accompanying environmental problems. Emphasis is being directed to the generation of sustainable energy by the fuel cell and water splitting technologies. Accordingly, the development of highly efficient electrocatalysts has attracted significant interest, as the fuel cell and water splitting technologies are critically dependent on their performance. Among numerous catalyst designs under investigation, nanoframe catalysts have an intrinsically large surface area per volume and a tunable composition, which impacts the number of catalytically active sites and their intrinsic catalytic activity, respectively. Nevertheless, the structural integrity of the nanoframe during electrochemical operation is an ongoing concern. Some significant advances in the field of nanoframe catalysts have been recently accomplished, specifically geared to resolving the catalytic stability concerns and significantly boosting the intrinsic catalytic activity of the active sites. Herein, general synthetic concepts of nanoframe structures and their structure‐dependent catalytic performance are summarized, along with recent notable advances in this field. A discussion on the remaining challenges and future directions, addressing the limitations of nanoframe catalysts, are also provided.

催化纳米框架及其他。

对化石燃料消耗的惊人速度以及随之而来的环境问题,导致了对可持续能源生产和支出的不断增长的需求。重点是通过燃料电池和水分解技术来产生可持续能源。因此,由于燃料电池和水分解技术关键取决于它们的性能,因此高效电催化剂的开发引起了人们的极大兴趣。在众多正在研究的催化剂设计中,纳米级框架催化剂的单位体积固有表面积大,并且其组成可调,这分别影响了催化活性位点的数量及其固有的催化活性。不过,纳米框架在电化学操作期间的结构完整性是一个持续关注的问题。最近已经实现了纳米框架催化剂领域的一些重大进展,特别是解决了催化稳定性问题并显着提高了活性位点的固有催化活性。在此,总结了纳米框架结构的一般合成概念及其与结构有关的催化性能,以及该领域的最新进展。还讨论了剩余的挑战和未来的方向,以解决纳米框架催化剂的局限性。特别适合解决催化稳定性问题并显着提高活性位点的固有催化活性。在此,总结了纳米框架结构的一般合成概念及其与结构有关的催化性能,以及该领域的最新进展。还讨论了剩余的挑战和未来的方向,以解决纳米框架催化剂的局限性。特别适合解决催化稳定性问题并显着提高活性位点的固有催化活性。在此,总结了纳米框架结构的一般合成概念及其与结构有关的催化性能,以及该领域的最新进展。还讨论了剩余的挑战和未来的方向,以解决纳米框架催化剂的局限性。
