Hydrogenation of acetone on technetium catalysts

Article abstract of DOI:10.1007/BF02495642

The catalytic properties of supported mono-and bimetallic catalysts of the Tc/support, M/support, and M-Tc/support types (M = Pt, Pd, Rh, Ru, Ni, Re, Co; supports are γ-Al₂O₃, 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 γ-Al₂O₃ as the support). The influence of support nature on the catalytic activity was investigated for the Rh-Tc system as an example. A nonadditive increase in the catalytic activity of Rh-Tc/γ-Al₂0₃ in comparison with monometallic catalysts was found. The state of the surface of the catalysts was characterized by the UV-VIS diffuse reflectance spectra.
