Abstract:
LiAl layered double hydroxides (LDH) are the promising compounds for application in base catalysis and as precursors of the supports for platinum catalysts. In the work, such systems were synthesized by mechanochemical method. The effect of composition of the initial mixture (Al(OH)3, Al(NO3)3, LiOH, LiNO3), material of milling bodies (steel or ceramic), and activation conditions (centripetal acceleration and activation time) on the properties of LiAl-LDH were studied. It was found that each of the synthesized systems is a polyphase one and contains not only the LDH phase but also the side phase of aluminum
trihydroxide. In addition, the samples obtained with the use of steel milling bodies have a substantial amount of iron. The use of ceramic milling bodies makes it possible to obtain the LiAl-LDH phase under relatively mild conditions (acceleration of 300 m/s2 and activation time of 15 min).
