Dataset of N-doped CuO:NiO mixed oxide thin film sensor for glucose oxidation

Abstract

In this data in brief article dataset of plasma-assisted nitro- gen doping of a binderless, spin-coated CuO-NiO mixed ox- ide thin film was presented (Palmer et al., 2020). A compari- son of the CuO, N–CuO/Cu 2 O, CuO:NiO and N–CuO/Cu 2 O:NiO are presented. The as prepared films were used for the ap- plication of a glucose sensor. The nitrogen doped species, generated during plasma ignition, resulted in a beneficial phase transformation of CuO to Cu 2 O. Characterisation tech- niques such as XPS, particle size distribution and EIS tech- niques were utilized to study the morphology, structural fea- tures, doping profile and electrical properties of the vari- ous developed electrodes. The electrochemical performance of the thin film sensors was tested using cyclic voltamme- try and chronoamperometry. The CuO exhibited a sensitivity of 830 μA/mM cm 2 up to 1.65 mM of glucose, N–CuO/Cu 2 O had a linear range up to 1.91 mM with a sensitivity of 873 μA/mM cm 2 and the CuO:NiO electrode had a linear range up to 1.65 mM with a sensitivity of 1103 μA/mM.cm 2
