Natural oil derived carbon nano-onions as a sensitive electrocatalyst for nitrite determination

Publication date: Available online 12 June 2019Source: Materials Chemistry and PhysicsAuthor(s): Aasiya Shaikh, Balwant Kr Singh, Smrutiranjan ParidaAbstractIn this communication, we report carbon nano-onions (CNOs) derived from natural oil as metal-free sensors for efficient nitrite determination. The pristine CNOs showed remarkable nitrite oxidation capability with a linear detection range of 1 μM to 90 μM (R2 = 0.998), the sensitivity of 214.29 μA mM-1 cm-2 and detection limit as low as 0.75 μM. The performance of this material exceed many well studied materials used as active materials for nitrite sensor.Graphical abstract
