CO
2 photoreduction into carbon-based chemicals has been considered as an appropriate way to alleviate the energy issue and greenhouse effect. Herein, the 5, 10, 15, 20-tetra (4-carboxyphenyl) porphyrin cobalt(II) (CoTCPP) has been integrated with BiOBr microspheres and formed the CoTCPP/BiOBr composite. The as-prepared CoTCPP/BiOBr-2 shows optimized photocatalytic performance for CO
2 conversion into CO and CH
4 upon irradiation with 300 W Xe lamp, which is 2.03 and 2.58 times compared to that of BiOBr, respectively. The introduced CoTCPP significantly enhanced light absorption properties, promoted rapid separation of photogenerated carriers and boosted the chemisorption of CO
2 molecules. The metal Co
2+ at the center of the porphyrin molecules also acts as adsorption center for CO
2 molecules, boosting the CO
2 convert into CO and CH
4. The possible mechanism of CO
2 photoreduction was explored by
in-situ FT-IR spectra. This work offers a new possibility for the preparation of advance photocatalysts.
