MOF-derived in situ growth of carbon nanotubes entangled Ni/NiO porous polyhedrons for high performance glucose sensor

The carbon nanotubes entangled Ni/NiO porous polyhedrons were obtained by in situ growing process with Ni-MOF precursor acting as both the carbon source and catalyst (Ni/NiO) source, which showed highly improved electrochemical performance. The enhanced glucose oxidation activity of Ni/NiO/CNTs may be due to the synergistic effect of metallic nickel and carbon nanotubes.
