Catalytic oxidation of ethylene to acetic acid on Pd-HPA/SiO2 catalysts with different heteropoly acids
The effect of different heteropoly acids (HPA) on the catalytic properties of Pd-HPA/SiO2 in the selective oxidation of ethylene to acetic acid was investigated in this work. The results demonstrated that a good balance of Bronsted acid sites and Pd2+ ions stabilized by Bronsted acid sites was an indispensable factor in producing acetic acid.
