【 摘 要 】

Conversion of cellulose to renewable and valuable chemicals has attracted global interest in order to build up sustainable development. The catalysts M-W/SBA-15 (M = Ni, Pd, Zn, Cu) were prepared to achieve selective conversion of cellulose via hydrogen donors. To be noted, the extra pure H2employed in this catalytic system only needed 2.0 MPa and the catalysis results shown a relative high yield of EG, reaching up to 42.2% at 230°C for 5 h. The isopropanol as the suitable hydrogen donor converted to acetone partially and pressurized the space in reaction system. The serial metallic catalysts were characterized and analyzed by H2-TPR, XRD, XPS and TEM. Some metal alloys were produced, evidenced by XRD, improved the yields of target products.
