) < Pd/C (HCI) < Pd/C (HNO₃) < Pd/C (H₂O₂). The values for specific surface area, pore size and pore volume all decreased after pretreatment by HCl and HNO₃, and presented a slight increase after pretreatment with H₂O₂. The dispersion performance of particles in Pd/C catalysts obtained with 25% hydrogen peroxide pretreatment was better and these particles' mean size was 8.0 nm. Pd crystallization degree for catalysts was lower after hydrogen peroxide pretreatment, and the crystalline grains were smaller.
