Wet chemical method is a relatively simple technique, which has been used for attaching nickel nanoparticles homogeneously on multi-walled carbon nanotubes (MWCNT). The MWCNT was synthesised by catalytic chemical vapour deposition (CCVD) method. The surface of MWCNT was modified by treating with boiling conc. nitric acid. Carbon nanotubes dispersed in nickel nitrate solution were heat treated with particular heating rate of 8°C/min from room temperature to 100°C under argon atmosphere and soaked at this temperature for 1 h before heating to 500°C at 4C/min. The resultant product is found to be nanostructured nickel oxide attached to MWCNT. Subsequent reduction of the metal oxide in hydrogen atmosphere yielded nickel nanoparticles anchored to the surface of nanotubes. Chemical impregnation resulted in homogeneously dispersed nickel particles on the surface of oxidised MWCNT whereas in the case of unoxidised MWCNT uneven dispersion of nickel particle was observed. Results obtained on the characterisation of the products from XRD, SEM, TEM and EDX are presented. This simple method could allow large-scale production of functionalised MWCNT, which can be used as catalyst supports with high stability.
