Synthesis of Nanowires by Spray Pyrolysis [PDF]

Journal of Sensors, 2009
Nanowires of carbon as well as nickel‐carbon (Ni‐C) were synthesized by spray‐pyrolysis. The carbon nanowires were synthesized using methanol as a precursor while the Ni‐C nanowires were obtained by using nickel chloride methanol solution as feed. It was found that low argon carrier gas flow rates (<100 cm3/min) and suitable reaction temperatures ...
