To develop an efficient catalyst system for hydroformylation of functionalized olefin containing-CN functional group,titania and Zr-doped titania nanotubes supported Rh-catalysts were synthesized. The catalysts were characterized with XRD,XPS,FT-IR,TEM and N2adsorption-desorption. The surface acidity of catalysts increased with the increase of Zr-content in the catalysts. XRD patterns for catalysts did not show the diffraction peak related to Rh,which should be ascribed to that Rh was highly dispersed on th...
