Abstract

Two kinds of carbon nanotubes (CNTs) with different inner diameter (less than 10 nm: CNTs-1 and between 60 and 100 nm: CNTs-2) were used as catalyst supports. The platinum particles were simply deposited on the outside surface (CNTs-1) and inside (CNTs-2) and were easily reduced to Pt by refluxing. The catalysts exhibit high activities in the selective hydrogenation of cinnamaldehyde which contains both C{double bond, long}C and C{double bond, long}O bonds. But the selectivity of these two catalysts was quite different under same reaction conditions. The high selective hydrogenation of C{double bond, long}O bond was observed over catalyst 3%Pt/CNTs-2, while the completely hydrogenation of b..
