Supported ruthenium was used in the liquid phase catalytic transfer hydrogenation of furfural. To improve the stability of Ru against leaching, phosphorus was introduced on a Ru/Al2O3 based catalyst upon impregnation with ammonium hypophosphite followed by either reduction or calcination to study the effect of phosphorus on the physico-chem. properties of the active phase. Characterization using X-ray diffraction, solid state 31P NMR spectroscopy, X-ray absorption spectroscopy, temperature programmed reduction with H2, IR spectroscopy of pyridine adsorption from the liquid phase and transmission electron microscopy indicated that phosphorus induces a high dispersion of Ru, promotes Ru reducibility and is responsible for the formation of acid species of bronsted character. As a result, the phosphorus-based catalyst obtained after reduction was more active for catalytic transfer hydrogenation of furfural and more stable against Ru leaching under these conditions than a benchmark Ru catalyst supported on activated carbon.
