Abstract
A method was developed for preparing hydrotalcite-type hydroxo salts containing zinc together with magnesium, aluminum, vanadium, molybdenum, and niobium in various combinations. The formation conditions for these hydroxo salts were studied by potentiometric titration; their samples were prepared and X-ray diffraction patterns were recorded. Samples of oxide catalysts for the oxidative dehydrogenation (ODH) of hydrocarbons were prepared by heat-treatment of the hydroxo salts. The catalytic activity of these catalysts was studied. Some catalysts showed high efficiency in ethane ODH reactions: they enhanced ethylene yield and reaction selectivity.
