Abstract:
A series of sponge-like Ni1-xMx (M = Cu, Co, Cr, Fe; x = 0.00-0.10) alloys was prepared via synthetic routes with subsequent reduction in H2 atmosphere at 800-1000 °C. Formation of Ni-based solid solutions with fcc (face-cantered cubic) lattice of nickel was proven by X-ray diffraction analysis for all prepared samples. Ni1-xMx alloys were explored as precursors for self-organizing catalysts active in processing of 1,2-dichloroethane into carbon nanomaterial (CNM). According to kinetic studies of CNM growth performed at 600 °C, the catalytic activity of Ni1-xMx samples changes as follows: Cr > Co ~ Cu >> Fe. Ni-Cr sample showed rather stable performance during 4 h whereas Ni-Co, Ni-Cu and Ni (reference) samples underwent rapid deactivation after ~150 min of reaction. The presence of the residual amount of Cr (0.5 at.%) found by energy dispersive X-ray microanalysis method in the composition of active Ni particles responsible for the growth of CNM is considered to be a key factor providing the stable catalytic performance. The obtained carbon product is represented by well-ordered segmented fibers (0.4-0.8 microns in diameter) and characterized with comparatively high textural parameters (surface area - 290-330 m2/g, pore volume – 0.43-0.57 cm3/g).
