Silica‐supported Pd, Rh and Pt metal nanoparticles catalyze the hydrogenolysis of the Pt−OPh bond of ( t bpy)Pt(OPh)Cl to release PhOH. Based on kinetic studies monitored by 1 H NMR spectroscopy, the reactivity trend is Pd>Rh>Pt. Kinetic studies with Pd/SiO 2 are consistent with a first‐order dependence on the catalyst and the molecular Pt(II) complex ( t bpy)Pt(OPh)Cl. Using TEM‐EDS mapping and ICP‐OES measurements of a recovered Pd catalyst, after 1 hour of hydrogenolysis of ( t bpy)Pt(OPh)Cl, approximately 10–16 % Pt deposition (relative to Pd mol %) on the Pd/SiO 2 surface was quantified.
