Abstract:

Nickel aluminate spinel (NiAl2O4) has received attention as a catalyst solid support due to its stability, strong resistance to acids and alkalis and high melting point. The properties and quality of the catalysts are heavily affected by crystal size, morphology, phase homogeneity and surface characteristics of the materials, which themselves are dependent on method and parameters of processing rout. In this work, we report on the fabrication of novel NiAl2O4 nanofibers covered by NiO nanolayer by combustion method.The XRD patterns show that the combustion technique was excellent to prepare NiO/NiAl2O4 nanofibers. The crystallite sizes of NiAl2O4 and NiO were found to be around 27 and 19 nm correspondingly. Scanning electron micrographs (SEM) and Energy dispersive X-ray (EDX) analysis showed that the NiO/NiAl2O4 nanofibers with more than 20 nm in diameter were consist of NiAl2O4 core and NiO outer layer.
