Abstract

Palladium particles were synthesized with 1-buthyl-3-methylimidazolium trifluoromethanesulfonate ([Bmim][$CF_3SO_3$]) as an effective solvent during the synthesis. The morphology of the particles was affected by the concentration of [Bmim][$CF_3SO_3$]. Furthermore, the palladium on carbon powder was prepared with various [Bmim][$CF_3SO_3$] concentrations and calcinations temperatures as a catalyst for hexafluoropropylene hydrogenation. Catalytic activity was varied by both conditions significantly. Under the identical condition, the catalyst prepared by the same mole ratio of [Bmim][$CF_3SO_3$] and palladium, and calcined at $500^{\circ}C$ was the most active in this reaction.

기능성 용매인 1-buthyl-3-methylimidazolium trifluoromethanesulfonate ([Bmim][$CF_3SO_3$])를 이용하여 팔라듐 입자를 제조하였다. 제조된 입자의 형상은 기능성용매의 농도에 영향을 받았다. 또한 hexafluoropropylene 수소화 반응용 촉매를 제조하기 위하여 탄소 담지 팔라듐 입자를 제조하였다. 촉매 제조 시 기능성용매의 농도와 소성온도를 변화해 가면서 최적의 촉매제조 조건을 구하고자 하였다. 수소화 촉매의 반응활성의 상기의 두 가지 제조조건에 따라서 크게 달라지는 것이 관찰되었다. 동일한 반응조건에서 기능성용매와 팔라듐 전구체의 몰 비가 동일하고 소성온도가 $500^{\circ}C$에서 제조된 촉매가 가장 우수한 반응성을 보였다.
