摘要

•Effect of support derivatization on activity of Pd catalyzed HDC of TCE is shown.•Lack of derivatization causes loss of support hydrophobicity and swellability.•Support swellability is essential to deposit Pd particles deep inside the pores.•Hydrophobicity protects the intrapore Pd by repelling hydrophilic HCl molecules.•TCE absorption in pores restricts HCl entry by creating localized non-polarity.
