Developing rechargeable Li-O2 batteries is an effective way to relieve current the energy stress and electricity shortage. Designing an oxygen electrode catalyst with superior bifunctional catalytic activity can significantly improve...

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...

The development of high-efficiency economic photocatalyst for the production of hydrogen peroxide (H2O2) is of great significance for solar-to-fuel conversion. Bismuth oxychloride (BiOCl) shows giant potential for photocatalytic H2O2 production,...

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.
