Abstract

In this perspective, we aim to explore the latest advancements in a range of design improvements in iron-based catalysts, with a particular focus on electron transfer during catalytic processes. Up to now, various design improvements have been employed to enhance the catalytic activity of heterogeneous iron-based catalysts, including adjustment of microstructure, introduction of support materials, construction of core–shell structures, and incorporation of new components. The effectiveness of these adjustments is contingent upon enhancing the interfacial electron transfer capabilities of heterogeneous iron-based catalysts. Accelerating electron transfer is a fundamental measure to enhance the catalytic ability of the catalyst. Particularly, the activation of pollutants and oxidants during the electron transfer process will lead to different activation mechanisms, combinations, and transformations of activation pathways. Furthermore, considering the practical applications of iron-based composite catalysts, we have also provided future research directions, which address some challenging issues and possible solutions. These directions are crucial for guiding future efforts in catalyst development and optimization.

过渡金属铁基催化剂的研究进展:通过电子转移增强催化活性
从这个角度来看,我们的目标是探索铁基催化剂的一系列设计改进的最新进展,特别关注催化过程中的电子转移。迄今为止,为了提高非均相铁基催化剂的催化活性,人们采用了各种设计改进方法,包括调整微观结构、引入支撑材料、构建核壳结构以及加入新组分等。这些调整的有效性取决于增强非均相铁基催化剂的界面电子转移能力。加速电子转移是提高催化剂催化能力的根本措施。特别是在电子转移过程中,污染物和氧化剂的活化会导致不同的活化机制、组合和活化途径的转变。此外,考虑到铁基复合催化剂的实际应用,我们还提出了未来的研究方向,解决了一些具有挑战性的问题和可能的解决方案。这些方向对于指导未来催化剂的开发和优化至关重要。
