Two mesoporous silicas (HMS) with high surface area and a pore diameter size of 2 nm were synthesized by a sol–gel method. Platinum catalysts were prepared with a 1 wt% metal content. A commercial silica supported catalyst was used for comparison. The catalysts were characterized by H2-TPR, TEM and 29Si-CP-MAS-NMR. The catalytic activity was measured by the hydrodechlorination of 1,2-dichloroethane...
