behavior were determined. To obtain insight into the role of ImCl-PF 6 during catalysis, an ImCl-PF 6 -free catalyst (W/SBA-15) was also synthesized. W-ImCl-PF 6 -SBA-15 and W/SBA-15 were investigated as catalysts for benzyl alcohol oxidation, as a model reaction, under solvent-free conditions with H 2 O 2 .The presence of ImCl-PF 6 was crucial for obtaining excellent catalytic activity, and W-ImCl-PF
