Cov tshuaj formula ntawm vanadium bismuth tetroxide yog [bi2o2] 2 [vo3.5-0.5] 2 -, nyob rau hauv uas lub qhov ncauj sawv cev rau cov pa oxygen ion vacancy inherent hauv cov pa octahedron. Lub pob xim tsaus nti hauv daim duab sawv cev rau Bi, thiab sab xis tshaj yog sawv cev rau bi2o22 . BiVO4 yog ib qho uas tsis yog-tio2 raws li pom lub teeb semiconductor photocatalyst. BiVO4 muaj peb cov qauv siv lead ua, uas yog monoclinic scheelite, tetragonal zircon thiab tetragonal scheelite. Ntawm lawv, thaum tetragonal zircon tuaj yeem hloov mus rau monoclinic scheelite qauv nyob rau hauv cov cua sov (thaum rhuab mus rau chemicalbook 670 ~ 670k), monoclinic scheelite thiab tetragonal scheelite hom kuj tuaj yeem hloov mus rau ib leeg (528k). Lub tetragonal monoclinic theem BiVO4 muaj qhov pom kev ua haujlwm siab tshaj plaws. BiVO4 nrog Scheelite qauv (monoclinic system) qhia tau hais tias zoo heev catalytic kev ua si nyob rau hauv pom lub teeb irradiation, thiab muaj ntau dua oxygen ntau lawm kev ua si tshaj li ib txwm photocatalyst WO3 (band gap 2.8ev). Lub quantum efficiency ntawm 450nm tuaj yeem ncav cuag 9%. Qhov no ua rau BiVO4 ntau dua thiab tseem ceeb hauv thaj tsam ntawm pom lub teeb catalysis.
