cze n-Butane oxidative dehydrogenation over VO(X)-HMS catalyst Na dvou seriích VOx-HMS katalyzátorů připravených impregnací a přímou syntézou byla studována oxidativní dehydrogenace n-butanu. Nejvyšší aktivita a selektivita na olefin byla dosažena na materiálech obsahujících vysoký podíl izolovaných monomerních VOx jednotek s tetraedrální koordinací. oxid vanadu; oxidativní dehydrogenace; n-butan; hexagonální mesoporézní silika; TPR; DR UV-vis
eng n-Butane oxidative dehydrogenation over VO(X)-HMS catalyst The role of particular VO(X) species supported on hexagonal mesoporous silica (HMS) in oxidative dehydrogenation (ODH) of n-butane was investigated on two sets of VO(X)-HMS catalysts prepared by wet impregnation and direct synthesis differing in amount and distribution of VO(X) species. The highest activity and selectivity to olefins were reached on materials with high content of isolated monomeric VO(X) units with tetrahedral coordination. vanadium oxide; oxidative dehydrogenation; n-butane; hexagonal mesoporous silica; TPR; DR UV-vis
