Promotional effect of bismuth as dopant in Bi-doped vanadyl pyrophosphate catalysts for selective oxidation of n-butane to maleic anhydride
Bismuth-promoted (1% and 3%) vanadyl pyrophosphate catalysts were prepared by refluxing Bi(NO3)3·5H2O and VOPO4·2H2O in isobutanol. The incorporation of Bi into the catalysts lattice increased the surface area and lowered the overall V oxidation state. Profiles of temperature programmed reduction (T...
