Green synthesis of Au/TS-1 catalysts via two novel modes and their surprising performance for propylene epoxidation
- 化学化工－已发表论文 
In this communication, we report on the preparation of active Au/TS-1 catalysts via two green modes, namely, sol-immobilization method and adsorption-reduction method by using plant extract. Experimental results manifested that bioreduction Au/TS-1 catalysts exhibited excellent performance in vapor phase propylene epoxidation with H(2)/O(2) mixture, especially in view of the fact that the optimal propylene conversion (12.6%) and H(2) efficiency (48.9%) are the highest in data reported so far. To our knowledge, this is the first attempt on the preparation of bioreduction Au/TS-1 catalysts for propylene epoxidation. (C) 2011 Elsevier B.V. All rights reserved.
