In this study, Li‐containing porous carbon materials were prepared from terephthalic acid and lithium hydroxide, and then loaded with different contents of copper oxide. After these materials were fully characterized with X‐ray diffraction, scanning electron microscope, Raman spectrum, nitrogen adsorption and desorption, and CO2‐TPD, their CO2 capture performance was measured. Results showed that the CO2 capture capacity of CuO(0.75)/LiC at 0 °C under 1 bar was as high as 142.8 mg‐CO2 g−1. However, excess CuO significantly reduced CO2 capture performance of the material. For example, the maximum adsorption capacity of CuO(2)/LiC was only 119.7 mg‐CO2 g−1. Meanwhile, with CO2/N2 mixed gas, these materials had significantly and selectively higher CO2 adsorption capacity over N2. Additionally, all of these lithium‐containing carbon‐based porous materials with supported copper oxide, including CuO(0.75)/LiC, could effectively capture CO2 with high selectivity and reproducibility.
