The mesoporous silica with three active metals (Al-Cu-M, M = Zn and Ga) was successfully prepared by one-pot synthesis method. The acid sites originated from Al hydrolyzed DME into methanol and Cu oxides were concerned in the step of the methanol steam reforming. Addition of Zn and Ga were expected to improve the activity for DME SR. The prepared catalysts were characterized with BET, XRD, NH3-TPD, SEM and TEM. The catalysts showed small crystallite size of metal oxide, mild acidity and high catalytic activity in the DME SR. The increase of the methanol consumption due to the advanced system of three active metals caused the improvement of the activity for DME SR. |
