Air oxidation of propylene over supported copper phthalocyanine

Selective oxidation of propylene over model supported V2O5 catalysts: Influence of surface vanadia coverage and oxide support

Selective oxidation of propylene to acrolein over supported V2O5/Nb2O5 catalysts: An in situ Raman, IR, TPSR and kinetic study

The vapor-phase selective oxidation of propylene (H2C CHCH3) to acrolein (H2C CHCHO) was investigated over supported V2O5/Nb2O5 catalysts. The catalysts were synthesized by incipient wetness impregnation of V-isopropoxide/isopropanol solutions and calcination at 450 8C. The catalytic active vanadia component was shown by in situ Raman spectroscopy to be 100% dispersed as surface VOx species on ...

The characteristics of wet air oxidation of phenol over CuOx/Al2O3 catalysts: effect of copper loading.

The nature of active copper species is well-known to vary with copper loading, i.e., isolated Cu(2+) to bulk CuO. In this work, however, the effect of copper loading on the activity and the selectivity was investigated for the wet oxidation of phenol over CuO(x)/Al(2)O(3) catalysts. The activity and the mineralization selectivity of the catalysts increased with copper loading up to 7wt% and rem...

Catalytic oxidation of airborne toluene by using copper oxide supported on a modified natural diatomite

The catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. The catalyst was prepared by the wet impregnation method and characterized by using the Brunauer Emmett Teller (BET), field emission Scanning Electron Microscopy (FESEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and Temperature-programmed reduction (TPR) analysis. The highest catalytic ...
