Many porous organic polymers (POPs) possess excellent light absorption capacity and CO 2 absorption performance owing to their conjugated skeletons and large specific surface area values. Some of these fascinating materials have inherent reaction sites for CO 2 conversion and appropriate band structures to catalyze the CO 2 reduction reaction. Therefore, these POPs have been used as heterogeneous catalysts in the photocatalytic CO 2 reduction reaction. Among those POPs, four kinds of catalytic systems have been developed for realizing the CO 2 photoreduction reaction: POPs loaded with noble metals, POPs loaded with non‐noble metals, POPs combined with inorganic semiconductors, and metal‐free POPs. Each of these catalytic systems has its own advantages and drawbacks. In general, the catalytic system of supported metals has higher catalytic efficiency but lower durability than metal‐free POPs. It should be noted that in the process of catalyst development, the co‐catalyst is gradually minimizing in POPs to achieve a more green CO 2 photoreduction reaction. In this review, different types of POPs and the relationship between their structures and catalytic performance in the photocatalytic reduction of CO 2 are summarized.
