제목 Supported Pd Catalyst Preparation using Liquid Carbon Dioxide
초록 Supported palladium (Pd) catalysts were prepared using a solvent-free and environmentally benign route. Pd (II) hexafluoroacetylacetonate (Pd(hfac)2) was impregnated from liquid carbon dioxide on a low surface area (13.6 m2/g) α-alumina and high surface area (207 m2/g) γ-alumina supports. The impregnated Pd(hfac)2 was reduced in hydrogen at 75 oC. Pd particle sizes on the α-alumina vary from 10 to 60 nm as Pd loading increases from 0.16 to 1.52 wt%. When the γ-alumina was used, Pd particle sizes vary from 2.7 to 6.9 nm as Pd loading increases from 0.58 to 3.94 wt%.
