摘要: Abstract The synthesis of vanadyl phosphate by reaction an alcoholic solution V 2 O 5 and o -H 3 PO 4 has been studied. solids obtained were investigated various physico-chemical techniques as in situ X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential thermal (DTA) under inert atmosphere. compounds have further characterized infrared UV–Visible spectroscopies. isopropanol conversion is carried out to evaluate the catalytic activity samples. increases with temperature from 433 503 K for phosphorus oxides calcined at a different temperature. However, attains 100% K, solid 973 exhibits high selectivity towards propene (100% K).
