| 英文摘要 | Some Ru and Co carbonyl clusters in zeolite pores such as Ru-3(CO)12/NaY, [HRu6(CO)(18)](-)/NaY, [Ru-6(CO)lg](2-)/NaX, Co-4(CO)(12)/NaY and Co-6(CO)(16)/NaY were prepared by the ship-in-bottle technique, and characterized by FTIR and EXAFS. The RuCo bimetallic carbonyl cluster was prepared by reductive carbonylation of the oxidized RuCo/NaY, which provides the proposed assignment to [HRuCo3(CO)(12)]/NaY. The tailored Ru, RuCo and Co catalysts were prepared by H-2 reduction from the precursors, e.g. Ru, RuCo bimetallic and Co carbonyl clusters impregnated on SiO2 and entrapped in NaY and NaX zeolites. The RuCo bimetallic carbonyl cluster-derived catalysts showed substantially higher activities and selectivities for oxygenates such as C-1-C-5 alcohols in CO hydrogenation (CO/H-2 = 0.33-1.0, 5 bar, 519-543 K). By contrast, hydrocarbons such as methane were preferentially obtained on the catalysts prepared from Ru-6, Ru-3 and Co-4 carbonyl clusters and provided lower CO conversion and poor selectivities for oxygenates. The RuCo bimetals are proposed to be associated with the selective formation of higher alcohols in CO hydrogenation. |
