Abstract
- Abstract: Two kinds of carbon nanotubes (CNTs) with different inner diameter (less than 10nm: CNTs-1 and between 60 and 100nm: 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 Pt0 by refluxing. The catalysts exhibit high activities in the selective hydrogenation of cinnamaldehyde which contains both Ce:glyph name="dbnd" />O bonds. But the selectivity of these two catalysts was quite different under same reaction conditions. The high selective hydrogenation of Cs observed over catalyst 3%Pt/CNTs-2, while the completely hydrogenation of both Ce:glyph name="dbnd" />O bonds was found over catalyst 3%Pt/CNTs-1.
