The catalytic properties of supported mono-and bimetallic catalysts of the To/support, M/support, and M--Tc/support types (M = Pt, Pd, Rh, Ru, Ni, Re, Co; supports are ),-A1203, MgO, SIO2) were investigated in the acetone hydrogenation. The main products of this reaction are isopropyl alcohol and propane. The catalytic activity in the acetone hydrogenation of the metals studied decreases in the consequence Pt > Tc ---Rh > Pd> Ru > Ni ~ Re > Co (with y-AI203 as the support). The influence of support nature on the catalytic activity was investigated for the R.h--Tc system as an example. A nonadditive increase in the catalytic activity of Rh--Tc/7-A1203 in comparisen with monometaUic catalysts was found. The state of the surface of the catalysts was characterized by the UV-VIS diffuse reflectance spectra.
