Ytterbium-Containing Magnesium–Aluminum Hydroxo Salts with a Hydrotalcite-Type Structure

Аннотация

A method is developed for inserting ytterbium into Mg–Al hydroxo salts that have a hydrotalcitetype layered structure, as well as for the chemical analyses of complex hydroxo salts containing ytterbium in various combinations with magnesium, aluminum, chromium, vanadium, molybdenum, and niobium. The formation conditions of these hydroxo salts have been studied by potentiometric titration, their samples have been prepared, and X-ray diffraction patterns recorded. The prepared hydroxo salt samples have been tested as precursors for oxide catalysts of oxidative dehydrogenation (ODH) of alkanes.
