The development of catalysts in selective hydrogenation of cinnamaldehyde to cinnamyl alcohol

This paper summarized the development of catalysts in selective hydrogenation of cinnamaldehyde to cinnamyl alcohol,including active components,supports,modificated reagents,the precursor and relevant theories. Further research directions,such as the study on selective catalysts over zeolites and carbon nanotubes,the mechanism of hydrogenation studied with insitu IR spectrum technology,the development of cheap catalyst and the continuous hydrogenation is fixed bed over ordinary pressure are also pointed out.
