Fak., Diss., 2014 %X V2O5/Nb2O5, V2O5/Al-x and V2O5/TiO2 and promoted Ni-Nb-M-O (M=Cr, Mo, W) catalysts were prepared by impregnation and evaporation methods, respectively. All these catalysts were characterized by several physico-chemical techniques. The catalytic performance of these solids was evaluated towards the ODHE in a fixed bed quartz reactor at 500-600 °C for supported vanadia samples and 300-450 °C for Ni-Nb-M-O catalysts. Special emphasis is devoted to gain deeper insights on the physico-chemical characteristics of the catalysts in relation to their activity/selectivity properties. %L 547.412045 %9 theses %9 Text %9 Hochschulschrift %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2015-0108-2 %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2015-0108-2&pdf %U http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2015-0108-2
