Preparation, characterization, and hydrogenation activity of new Rh0-MCM-41 catalysts prepared from as-synthesized MCM-41 and RhCl3

Ammonium template facilitates incorporation of Rh(III) in the as-synthesized MCM-41 in ethanol, thus affording, after an ex situ reduction step, catalytically active dispersions of Rh(0) with a high cis selectivity in the hydrogenation of disubstituted arenes.88
