Catalysts with the Mo1V0.3Te0.23Nb0.12Bi0÷0.05 compositions were prepared via spray-dry method and tested in ethane oxidative dehydrogenation (ODE) reaction. The maximum activity, selectivity to ethylene and stability in reaction conditions were obtained for Bi/Mo=0.015÷0.025. These samples had the highest M1 amount among modified samples. Modification of the M1 phase by Bi3+ results in hindering of Te segregation along the six-membered channels and preventing of the Te. Bi incorporation in the channels of the M1 phase and its possible participation in active ensembles are assumed to be responsible both for the stability and enhanced catalytic properties of the M1 phase. A further increase of the bismuth content (Bi/Mo = 0.05) was accompanied by a decrease of the M1 particle size and structural disordering.
