The generation of H2O2 on BiOCl(001) originates from O2 reduction, while there are two pathways on BiOCl(010).

In this work, we report a novel phosphorus element heterostructure with snowflake-like morphology consisting of 1D rod black phosphorus (BP) and 2D flake red phosphorus (RP). The content of black...

In this work, a novel BP@AuÀ Ag nanohybrid is fabricated by a facile ultrasonic method. A glassy carbon electrode (GCE) modified with these nanohybrids is found to be a viable enzyme-free sensor for H 2 O 2 detection. The deposition of Au nanoparticles on black phosphorus (BP) nanosheets enhances the stability of the electrode. Subsequent decoration of silver nanoparticles further dramatically improves the electrochemical performance owing to the synergetic effect. The as-prepared BP@AuÀ Ag/GCE displays excellent peak current response for H 2 O 2 reduction with a wide linear range (0.005-2.36 mM), low detection limit (1.09 μM), good stability, and negligible interference. The present work provides a new avenue for exploring novel BP-based enzyme-free biosensors.
