Аннотация

Effect of LiCoO2 support prepared by traditional ceramic and mechanochemical route on the activity of Rh and Pt catalysts in the reaction of NaBH4 hydrolysis was studied and compared with traditional supports, such as γ-Al2O3, TiO2 (anatase) and carbon (sibunit). Catalysts supported on LiCoO2 prepared using mechanical activation were found to have the highest catalytic activity. However, the endurance tests of 1 % Rh-LiCoO2 и 1 % Pt-LiCoO2 catalysts showed their gradual degradation. To understand the reason of this phenomenon, the interaction of LiCoO2 with NaBH4 solution was studied by XRD, FTIR, DRS and TEM.
