Vanadium phosphorous oxide (VPO) is the commercial catalyst for the selective oxidation of butane to maleic anhydride. A 1% bismuth-doped VPO catalyst was prepared by refluxing Bi(NO3)3 and VOPO4·2H2O in isobutanol (denoted as VPD). Bismuth incorporation into the VPO lattice lowered the overall V ox...
