Abstract
AbstractIn this work, a novel BP@Au−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 H2O2 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@Au−Ag/GCE displays excellent peak current response for H2O2 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.
