Electrosynthesis of bismuth nanodendrites/gallium nitride electrode for non-enzymatic hydrogen peroxide detection

A novel non-enzymatic H2O2 sensor was fabricated by electrodepositing BiNDs onto planar GaN electrode. The BiNDs/GaN sensor exhibited good sensitivity, reproducibility, and long-term stability towards H2O2 detection. The as-prepared BiNDs/GaN sensor was promising to detect H2O2 in real samples.138
