| Abstract | 用石墨烯（Graphene nanosheets, GNS）作为促进剂，制备一种高效新型的CuO-ZnO-Al2O3催化剂，考察其对CO2加氢制甲醇的催化性能．实验结果显示，在10%GNS- CuO-ZnO-Al2O3催化剂上，3.0MPa，523 K，V(H2):V(CO2):V(N2)=69:23:8，GHSV= 12000 mL/(h.g)的反应条件下，甲醇的时空收率为670 mg/h.g，分别是相同条件下无促进的CuO-ZnO-Al2O3和碳纳米管(CNT)促进的相应值(331和460)的2.08和1.46倍；催化剂的表征结果显示GNS的添加促进了活性物种的分散，提高催化剂的比表面积，而且10%GNS- CuO-ZnO-Al2O3催化剂对H2有优良的吸附活化能力。 |
| Other Abstract | A type of Graphene-promoted CuO-ZnO-Al2O3 catalyst was developed．This catalyst displays excellent performance for CO2 hydrogenation to methanol. Over a 10%GNS-CuO-ZnO-Al2O3 catalyst under reaction conditions of 3.0MPa, 523 K, V(H2):V(CO2):V(N2)=69:23:8 and GHSV= 12000 mL/(h.g), the space time yield(STY) of methanol reaches 670 mg/h.g. This value was 2.08 and 1.46 times that (331 and 460 mg/h.g) of the pure CuO-ZnO-Al2O3 and 10%CNT-CuO-ZnO-Al2O3, respectively, under the same reaction conditions. Characterization of the catalyst revealed that the particles on the GNS surface showed smallest size, most uniform size distribution and highest dispersion, and the GNS-promoted catalyst has biggest surface areas. Moreover, the excellent capability of the GNS-promoted catalyst for adsorbing and activating H2 played an important role in facilitating the increase of rate of surface CO2 hydrogenation reactions. |
