Porphyrin-based frameworks, as specific kinds of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), have been widely used in energy-related conversion processes, including the oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and CO2 reduction reaction (CO2RR), and also in energy-related storage technologies such as rechargeable Zn-air batteries. This review starts by summarizing typical crystal structures, molecular building blocks, and common synthetic procedures of various porphyrin-based frameworks used in energy-related technologies. Then, a brief introduction is provided and representative applications of porphyrin-based frameworks in ORR, OER, Zn-air batteries, and CO2RR are discussed. The performance comparison of these porphyrin-based frameworks in each field is also summarized and discussed, which pinpoints a clear structure-activity relationship. In addition to utilizing highly active porphyrin units for catalytic conversions, regulating the porous structures of porphyrin-based frameworks will enhance mass transfer and growing porphyrin-based frameworks on conductive supports will accelerate electron transfer, which will result in the improvement of the electrocatalytic performance. This review is therefore valuable for the rational design of more efficient porphyrin-based framework catalytic systems in energy-related conversion and storage technologies.
基于卟啉的框架作为特定类型的金属有机框架（MOF）和共价有机框架（COF），已广泛应用于与能源相关的转化过程，包括氧还原反应（ORR）、析氧反应（OER）和二氧化碳还原反应（CO2RR），还应用于诸如可充电锌空气电池等与能源相关的存储技术。本综述首先总结了用于与能源相关技术的各种基于卟啉的框架的典型晶体结构、分子构建单元和常见合成方法。然后，进行简要介绍并讨论基于卟啉的框架在ORR、OER、锌空气电池和CO2RR中的代表性应用。还总结并讨论了这些基于卟啉的框架在每个领域的性能比较，明确了结构-活性关系。除了利用高活性的卟啉单元进行催化转化外，调节基于卟啉的框架的多孔结构将增强传质，在导电载体上生长基于卟啉的框架将加速电子转移，这将导致电催化性能的提高。因此，本综述对于在与能源相关的转化和存储技术中合理设计更高效的基于卟啉的框架催化系统具有重要价值。
