3D CoxP@NiCo-LDH heteronanosheet array: as a high sensitivity sensor for glucose

Abstract The development of an efficient and convenient non-enzymatic glucose (Glu) sensor is an extremely attractive and challenging subject. In this work, a 3D cobalt phosphide coated nickel-cobalt layered double hydroxide heteronanosheet array on Ni foam (CoxP@NiCo-LDH NSA/NF) was constructed using electrodeposition and high-temperature phosphating technology. Its unique heteronanosheet array structure and synergistic effect resulting in excellent electrochemical activity for Glu. The response time of the sensor is ultra-fast (
