Abstract
Shape-controlled palladium nanocrystals were loaded onto mesoporous silica SBA15 and
studied in the hydrogenation of furfural and 5-HMF. Physio-chemical characterizations
of the catalysts were conducted by nitrogen physisorption, ICP-MS, XPS, TPR, H2
chemisorption, TEM and FT-IR spectroscopy. Catalytic tests were implemented in Parr
high pressure autoclave and in liquid phase with very mild condition. By comparing the
selectivity of the reaction, it was determined that the cubic palladium nanocrystals have a
preference to hydrogenate the aldehyde bond in these compounds, while octahedral
palladium nanocrystals prefer C=C double bond hydrogenation on furan ring. FT-IR
results also support this observation.
