Pt/γ-Al2O3 catalytic membranes vs. Pt on γ-Al2O3 powders in the selective hydrogenation of p-chloronitrobenzene

The catalytic activity of Pt/γ-Al2O3 membrane reactors, prepared using mesitylene solvated platinum atoms as source of active Pt particles, has been compared with that of analogously obtained Pt/γ-Al2O3 powders in the liquid phase hydrogenation of p-chloronitrobenzene. A largely different behaviour...

Description
Summary:The catalytic activity of Pt/γ-Al2O3 membrane reactors, prepared using mesitylene solvated platinum atoms as source of active Pt particles, has been compared with that of analogously obtained Pt/γ-Al2O3 powders in the liquid phase hydrogenation of p-chloronitrobenzene. A largely different behaviour has been observed, the membrane reactor acting as a H2 richer system.
