Pt-loaded P-MCM-41 as a novel bifunctional catalyst for catalytic combustion of trichloroethylene

Pt-loaded P-MCM-41 catalysts with different Si/P ratio were prepared and used as novel bifunctional catalysts for catalytic combustion of trichloroethylene (TCE). Acidic materials, ZSM-5, P-SiO2 and Al2O3 as supports in Pt-loaded catalysts were also studied for comparison. The high activity for TCE conversion and low selectivity to tetrachloroethylene were observed on Pt/P-MCM-41 catalysts, indicating that phosphorus modified MCM-41 with an amount of weak Brønsted acid sites, in combination with Pt, was effective to form a bifunctional catalyst.
