Abstract Herein, the novel ficus-iacertiolia fruit-derived porous graphene-like nanosheets (PGNSs) with rich active functional groups were synthesized via a high-efficient and low-cost one-step carbonization technique for H2O2 biosensor. Target electrode materials have promising porous structures with a large specific surface area (S-a) of 480.67 m(2) g(1). The modified glassy carbon electrode (PGNSs/GCE) was constructed and exhibited excellent electrocatalytic activity, showing a high-efficiency detection of H2O2, high sensitivity of 6.17 mu A mM(1) cm(2), a low detection limit of as low as 2.75 mu M and a wide linear range of 0.2-19 mM. Thus, this work demonstrates fundamental insights for the porous and active functional groups on electrodes, and provides a facile route to fabricate a highly sensitive H2O2 sensor for practical aspergillus flavus diagnosis.
