▎ 摘　　要

N-doped graphene (NG) incorporated Cu-ZnO-Al2O3 (CZA) catalysts were prepared by co-precipitation method and their catalytic performances for CO2 hydrogenation to methanol were evaluated under the reaction conditions of 200 C-White circle and 3.0 MPa. The results indicate that NG promotes effectively the dispersion of CZA and changes the electron structure of CZA, which could provide synergistic effect for methanol synthesis. When NG content is 10 wt.%, the CO2 conversion and methanol selectivity can achieve the highest values of 8.2% and 84%, respectively, which are much higher than those of traditional CZA catalyst.
