Abstract:
Bimetallic alloys Ni1-x-Mx (M=Co, Cu, Fe, Cr, Mo; x=0.01÷0.5) were synthesized by various methods (coprecipitation,
mechanochemical activation) to be used as precursors for preparation of self-organized catalysts active in production of carbon nanomaterials. Suggested approach is based on metal dusting (MD) of Ni-based alloys in aggressive reaction
atmosphere containing chlorinated hydrocarbons and H2. Ni-Mo precursor was found to give the most active catalyst while the best stabilizing effect was elucidated for the addition of Cr. Disintegration of starting alloys results in formation of the active metallic sites catalyzing multi-directional growth of carbon fibers of submicron diameter and segmented morphology. Due to defective structure, the obtained carbon product is characterized with high surface area (up to 400 m2/g) and porosity (0.5-0.8 cm3/g). The effect of M and its concentration in Ni-M precursor upon catalytic activity and structural peculiarities of CNM product being formed will be discussed in details.
