Abstract:
Nickel modified graphite screen printed electrodes are explored towards the sensing of alcohols in alkaline solutions. Electrolytically formed nickel microrods with average lengths and diameters of 12 μM and 2 μM respectively are shown to be readily formed on the surfaces of graphite screen printed electrodes. This is the first example of electrolytically formed nickel nanorods which exhibit electro-catalysis towards the sensing of ethanol over the range 2.6-23 mM and glycol over the range 230-1840 μM with limits of detection of 1.4 mM and 186 μM respectively.
