Photocatalytic CO 2 reduction is a promising technology to mitigate environmental issue and the energy crisis. The four nitrogen atoms in the porphyrin ring can incorporate transition metals to form stable active sites for CO 2 activation and photoreduction. Nevertheless, the photocatalytic efficiency of metalloporphyrins is still low due to the insufficient photoelectron injection to drive CO 2 photoreduction upon visible light irradiation. To address this issue, considerable efforts have been made to introduce photosensitizers for constructing homogeneous or heterogeneous metalloporphyrin‐based photocatalytic systems. In this Review, recent advances of metalloporphyrin‐based materials for visible‐light‐driven CO 2 reduction were summarized. The methods for the modulation of photosensitizing process at molecular level were presented for the promotion of photocatalytic performance. The mechanism of CO 2 activation and photocatalytic conversion was illustrated. Better insight into the structure‐activity relationship provides guidance to the design of metalloporphyrin‐related photocatalytic systems.
