Abstract
Synthesis of nitrogen doped graphene nanosheets (NGS) with controlled structure is a burgeoning issue in the field of materials chemistry. Herein, we for the first time report a novel, green, low-temperature, hydrothermal synthesis of two dimensional (2D), porous, NGS from carbon nanosheets (CNS) as precursor materials. Hydrothermal reduction of CNS not only imparts crystallinity to the material but also results in a substantial removal of oxygen functionalities, forming NGS. The as-synthesized NGS displayed excellent electrochemical sensing properties with high selectivity and sensitivity for the detection of dopamine (DA) in h
