带有不成对电子的物种，包括顺磁性氧化还原金属中心、表面缺陷中心、活性氧物种、吸附的自由基阴离子，通常参与催化反应。这些物种可以很容易地和彻底的询问使用电子顺磁共振（EPR）光谱，提供信息的身份，化学成分，甚至动力学的中心本身，从而有助于阐明参与的自由基的反应周期。本文综述了EPR在多相、均相、光催化和微孔材料中的应用，这些都是催化领域的重要研究内容。
Species bearing unpaired electrons, including paramagnetic redox metal centres, surface defect centres, reactive oxygen species, adsorbed radical anions, are often involved in catalytic reactions. These species can be readily and thoroughly interrogated using Electron Paramagnetic Resonance (EPR) spectroscopy, providing information on the identity, chemical composition and even the dynamics of the centres themselves, thereby helping to elucidate the involvement of the radicals in the reaction cycles. This review will summarise and highlight the applications of EPR in heterogeneous, homogeneous, photocatalytic and microporous materials, all of which are of vital importance to the field of catalysis.
