【摘要】 用 TPR、TPD、TPA法研究了 Ni6(CO) 12 /C和 Ni(C2 H8N2 ) 2 +2 /C催化剂的还原及吸脱附性能 ,并与传统的催化剂 (用镍盐制备 )进行了比较 ,得出初步的结果 :镍金属簇催化剂表现出特殊的吸附行为 ;镍催化剂的吸附行为表现出某一共同的本质特性更多还原

【Abstract】 Adsorption and reduction and desorption effects of the catalysts Ni6(CO) 12 and Ni(C2 H8N2 ) 2 +2 carried on the active carbon is researched by using Temperature Programmed Reduction(TPR) and Tem- perature Programmed Desorption (TPD) and Temperature Programmed Adsorption (TPA) ,and compared with the traditional catalysts preparation from nickel salt. The adsorption of the nickel cluster catalyst is of something special,and the adsorptions of nickel catalysts are of the same character.更多还原
