High quality Pt-graphene nanocomposites for efficient electrocatalytic nitrite sensing

- Pt nanoparticles-reduced graphene oxide composites are fabricated by one-pot hydrothermal method.
- The composite has an enhanced electrochemical activity toward the oxidation of nitrite.
- Amperometric response presents an especially high sensitivity of 496.4 μA mM−1.
- The prepared electrode is used as a sensor for the determination of nitrite in beverage samples.
