摘  要:鉴于对清洁和可持续能源的需求,来自金属有机框架(MOFs)的纳米炭衍生物正崭露头角,成为电催化能量转化的独特催化剂。这些MOF衍生的纳米炭材料不仅保持了MOFs组成可定制和结构多样性等优势,而且在热解过程中可有效防止金属纳米颗粒和金属氧化物的聚集。因此,它们提高了电催化效率,改善了电导率,并在燃料电池和金属-空气电池等绿色能源技术中发挥了关键作用。该综述以MOF衍生碳基材料的炭化机制为起点,随后深入探讨了固有炭缺陷、金属和非金属原子掺杂,并研究了这些材料的合成策略。此外,全面介绍了先进的表征技术,包括原位映射和原位光谱学。最后,对MOF衍生碳基材料作为电催化剂的研究前景提供了见解。该综述的主要目标是为当前MOF衍生碳基电催化剂的状况提供更清晰的视角,鼓励更高效电催化材料的发展。Because of the demand for clean and sustainable energy sources,nanocarbons,modified carbons and their composite materials derived from metal-organic frameworks(MOFs)are emerging as distinct catalysts for electrocatalytic energy conversion.These materials not only inherit the advantages of MOFs,like customizable dopants and structural diversity,but also effectively pre-vent the aggregation of nanoparticles of metals and metal oxides during pyrolysis.Consequently,they increase the electrocatalytic ef-ficiency,improve electrical conductivity,and may play a pivotal role in green energy technologies such as fuel cells and metal-air batteries.This review first explores the carbonization mechanism of the MOF-derived carbon-based materials,and then considers 3 key aspects:intrinsic carbon defects,metal and non-metal atom doping,and the synthesis strategies for these materials.We also provide a comprehensive introduction to advanced characterization techniques to better understand the basic electrochemical catalys-is processes,including mapping techniques for detecting localized active sites on electrocatalyst surfaces at the micro-to nano-scale and in-situ spectroscopy.Finally,we offer insights into future research concerning their use as electrocatalysts.Our primary object-ive is to provide a clearer perspective on the current status of MOF-derived carbon-based electrocatalysts and encourage the develop-ment of more efficient materials.
