Polydimethylsiloxane (PDMS) and 1‐butyl‐3‐methylimidazolium trifluoroacetate ionic liquid (IL) modified palladium‐based catalyst supported on activated carbon have been prepared and measured for hydrodechlorination of 4‐chlorophenol (4‐CP) using (HCOOH + HCOONa) as hydrogen source. For turnover frequency of 4‐CP HDC reaction to obtain a value of 3.0×10 5 h −1 and five times better than the value of the catalyst without PDMS. This may be due to the addition of PDMS which can promote the dispersion of the nanoparticles. The conversion of the catalyst HDC decreased from 100 % to 92 % after 5 times which may be due to a hydrophobic structure formed in the catalyst after the addition of PDMS.
