DRIFTS STUDIES OF ACRYLONITRILE ADSORPTION ON Pd/SdO2 AND PdSd/SdO2

DRIFTS STUDIES OF ACRYLONITRILE ADSORPTION ON Pd/SdO2 AND PdSd/SdO2

The acrylonitrile adsorption over Pd/SiO2 and PdSn/SiO2 catalysts wasprepared by "Solvated Metal Atom Dispersion" (SMAD) and analyzed by DRIFTS FTIR are studied. The catalysts were used in pellets and treated with dry N2(g) flow inside a flask in contact with the acrylonitrile vapours for...
