摘要: Abstract V2O5/CeF3 catalysts with 2.4–15.2 wt.% of V2O5 were prepared by wet impregnation method. The characterized BET surface area and pore size distribution, powder X-ray diffraction FT-IR. It was found that the formation Cerium Vanadate (CeVO4) occurs during stages catalyst preparation. studies revealed presence crystalline CeVO4 phase. lines due to phase increase in intensity amount (wt.%) catalysts. FT-IR investigation also showed increasing loadings V2O5. shift pore-size distribution lower range increased volume confirmed structure catalytic activity for ammoxidation 3-picoline nicotinonitrile on as a function loading CeF3 has been studied. continuous is responsible higher
