摘要：

Catalysts prepared by a condensation reaction of Rh(CO)2(acac) within the supercages of zeolite Y made basic by treatment with NaN3 are active for CO hydrogenation and selective for low-molecular-weight olefins and methanol. High partial pressures of CO (or CO + H2) stabilize the catalyst. The predominant species in the catalyst are suggested to be rhodium carbonyl clusters trapped in the zeolite cages.
