An experimental setup was created to produce deposited heterogeneous catalysts by
laser ablation of a metal target in the presence of various carriers in supercritical
carbon dioxide (SC-CO₂). The conditions of pulsed laser exposure (wavelength,
frequency, and time), SC-CO₂ medium parameters (pressure, temperature) and the
configuration of experimental setup (laser, target, carrier and visual and optical control
elements) were worked out. A composite consisting of Al₂O₃ with Pd particles was
obtained by laser ablation of metal palladium with deposition onto γ-alumina in a SCCO₂
medium. The synthesized composite has been studied as a catalyst for liquidphase
hydrogenation of di phenylacetylene and its high activity (TOF = 1.45 s^-1) and
high selectivity in hydrogenation of one triple bond has been shown.
