The experiment results show that the yield of hexane catalyzed by the nano-fibrous catalyst was 4.7 times higher than that of PdCl_2/γ-Al_2O_3 catalyst. The hydrogenation ofα-tetradecylene, cyclohexene, nitrobenzol and styrene by the nano-fibrous catalyst was also studied, the selectivity to primary products of the hydrogenation of cyclohexene, nitrobenzol and styrene was 100%.
