Facile Synthesis of Nickel Based Alloy Microtube by Using Spider Silk as Template and its Catalytic Property

Abstract:

Nickel based alloy microtube was prepared by utilizing spider silk as template via electroless deposition. The spider silk fiber was choosed as template which can be removed easily by heat-treatment and dissolving with sodium hydroxide solution. The nickel based alloy microtube was characterized by TG-DSC, XRD, SEM and EDX. SEM show that the microtube is about 600nm in outer diameter, 400 nm in inner diameter and more than 20 μm in the length. The catalytic activity of different structure Ni-P products was studied in liquid-phase hydrogenation of nitrobenzene reaction. The results show that the catalytic property of amorphous nickel based alloy is better than crystalline nickel based alloy and Raney Ni.
