Three-dimensional (3D) nickel foam supported Ni 2 P/NiO/CeO 2 nanoflake arrays (NFAs) were synthesized by hydrothermal, anneal and low-temperature phosphatizing processes. As-prepared samples were systematically researched by SEM, XRD, XPS, TEM, EDS and HRTEM technology. Cyclic Voltammgrams and Chronoamperometry technology were used to measure the sensors performance of Ni 2 P/NiO/CeO 2 NFAs. The results indicated that non-enzymatic glucose sensors based on Ni 2 P/NiO/CeO 2 NFAs exhibited a high sensitivity of 28.23 mA cm −2 mM −1 and good anti-interference ability, suggesting that the 3D nickel foam supported Ni 2 P/NiO/CeO 2 NFAs as a non-enzymatic glucose sensor is promising for practical applications.
