Deposition of Pd into mesoporous silica SBA-15 using supercritical carbon dioxide
Pd was deposited into mesoporous silica SBA-15 using supercritical CO2 (scCO2).
Palladium hexafluoroacetylacetonate [Pd (hfac) 2] was dissolved in scCO2 and impregnated
into the support at very mild conditions, 40° C and 85bar. Then the organometallic precursor
was reduced with H2 in the CO2 mixture or, after depressurization, in pure H2. Materials
were characterized by TGA, XRD, TEM, SEM, EDX, ICP-OES and N2-adsorption
experiments. Pd nanoparticles evenly distributed into the support (1–3mol% Pd by ICP-OES) …
