TGA-FTIR OF PdSn FINE SOLID SUPPORTED ON MgO: CYCLOHEXENE REDUCTION

PdSn bimetallic colloids by direct evaporation of solvent and simultaneous cocondensation with metals by chemical liquid deposition (CLD) method were obtained. The evaporation of solvents produces fine divided solids, which exhibit the carbonaceous species incorporated. This is corroborated by FT-IR...
