Sažetak

Vanadijum-molidben oksidi naneti na podloge od Al2O3, CeO2 i TiO2 mokrim postupkom karakterisani su primenom rentgenske difrakcione analize, adsorpcijom azota, UV-Vis spektroskopijom, merenjem električne provodljivosti i testiranjem aktivnosti u reakciji oksidativne dehidrogenizacije izobutana. Katalitičke osobine osobine oksidativne dehidrogenizacije izobutana u temperaturnom intervalu 400-550°C zavise od prirode nosača i sadržaja VMoO vrsta na nosaču. Katalizatori naneti na aluminijum-oksid su mnogo aktivniji od katalizatora koji su naneti na titanoksid ili cerijum-oksid.
