Abstract: 1, 8-Diazabicyclo [5.4.0] undec-7-ene (DBU) loading on MCM-41 (MCM-41- (DBU-Y)) was synthesized by dipping the DBU into the mesoporous MCM-41channels for the adsorption of CO2. The as-prepared MCM-41- (DBU-Y) was characterized using Scanning Electron Microscopy (SEM), Thermal Gravimetric Analysis (TGA), Automatic Gas Adsorption Analyzer (BET), and other methods. Studies on fixed-bed adsorption demonstrated that MCM-41-(DBU-Y) had excellent adsorption properties as CO2 adsorbent. The results of CO2 adsorption revealed the beneficial effect of utilizing MCM-41and DBU, resulting in a CO2 adsorbent with easy operating and high adsorption properties. At room conditions, the CO2 adsorption capability on MCM-41- (DBU-Y) increased first and then decreased with the increase of the load rate of DBU and total flow of simulated flue gas; The best regeneration temperature was 80 °C; The volume fraction ratio of CO2 and H2O was 1: 1 in the simulated flue gas, the adsorbent MCM-41- (DBU-Y) had an optimum CO2 adsorption capacity; MCM-41- (DBU-Y) was stable after five times adsorption/desorption cycles, indicating that the synthesized adsorbent was renewable. This indicated that MCM-41- (DBU-Y) demonstrated effective CO2 capture characteristics.
