6 The Synthesis of M esoporous ZnO by Hydrothermal and Performance of Pd /m2zno Catalyst for Steam Reform ing of M ethanol X IONG Guang2wei, LUO Lai2tao 3, L I Chang2quan ( Institu te of Applied Chem istry, N anchang U niversity, N anchang, , China) Abstract: M esoporous ZnO (m 2ZnO ) had been synthesized using hydrotherm al method and triblock copolym er Plu2 ronic F2127 ( F2127) as temp late reagent. The catalytic activities of Pd /m 2ZnO catalyst were studied w ith steam re2 form ing of methanol as p robe reaction. These samp les were characterized by m eans of BET, FT2IR, XRD, TEM and H 2 2TPR methods. The results showed that the p repared m2zno exhibited much higher BET surface area (124. 7m 2 /g) than those of nonmesoporous ZnO and literature value ( m 2 /g). A s compared with Pd /ZnO catalyst, Pd /m 2ZnO catalyst has higher dispersion and stronger interaction between Pd and ZnO, thus Pd /m 2ZnO catalyst exhibited much higher catalytic activity, H 2 yield, CO 2 selectivity and stability for steam reform ing of metha2 nol. The activity, H 2 yield and CO 2 selectivity of Pd /m2zno catalyst enhanced 38. 4% 44. 4% and 30. 0% than that of Pd /ZnO catalyst at 250, respectively. After continuum reaction 100 h, the activity of Pd /m2zno catalyst was 95% and only droped 4. 9%. Key words: M esoporous zinc oxide; Steam reform ing of methanol; Pd2based catalyst; Temp late reagent
