In this study, nano-donut shaped nickel oxide (NiO) nanostructures were synthesized using a simple low-temperature hydrothermal process. The synthesized nanostructures were characterized to have large quantity and relatively uniform morphology. The nano-donut shaped NiO nanostructures were used to fabricate electrochemical based non-enzymatic glucose sensors, which exhibited high sensitivity and low detection limit. These nanostructures have the potential for electrochemical sensing of other biochemical analytes.
In this study, we report the synthesis of nano-donut shaped nickel oxide (NiO) nanostructures using a simple low-temperature hydrothermal process. The detailed characterizations of nano-donut shaped NiO confirm that the as-synthesized nanostructures are grown in large quantity with relatively uniform morphology. Using the nano-donut shaped NiO nanostructures, the electrochemical based non-enzymatic glucose sensors were fabricated and their catalytic properties towards glucose electro-oxidation were conducted in alkaline media. The sensing results revealed the high sensitivity (904.6 mu A mM(-1) cm(-2)) and low detection limit (1.4 mu M). Owing to the high glucose sensing performance, the nano-donut shaped NiO nanostructures with a unique two-dimensional morphology and high specific surface area have the potential for electrochemical sensing of other biochemical analytes.
