A novel reduction method using argon non-thermal plasma was applied to Pd supported on SiO2 with a thin layer of ionic liquid. The investigation includes several ionic liquids, such as [Bmim][PF6], [Emim][BF4], etc. Ar plasma appears to be an effective way to replace conventional reduction procedure using hydrogen for Pd on supported ionic liquid catalysts. However, its effectiveness depends on the ionic liquid used. The results demonstrate that electrons generated by gas plasma can penetrate ionic liquid and effectively reach to Pd precursors for reduction in a short period of time. The plasma reduction method is unique and can have a wide application in reducing metal precursors in the presence of ionic liquids for various catalytic reactions.
