“…2 ). The binding energy of the O1s spectrum at 529.1 eV also confirms the existence of NiO [ 12 , 16 ] and 532.1 eV correspond to the formation of Cu 2 O [ 7 , 16 ] within the plasma treated CuO:NiO electrode. The N1s spectrum suggest that pyrrolic nitrogen is present due to the peak of 399.3 eV, which corresponds to a M–N bond [12] .…”

In this data in brief article dataset of plasma-assisted nitrogen doping of a binderless, spin-coated CuO-NiO mixed oxide thin film was presented (Palmer et al., 2020). A comparison 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 application 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 techniques such as XPS, particle size distribution and EIS techniques were utilized to study the morphology, structural features, doping profile and electrical properties of the various developed electrodes. The electrochemical performance of the thin film sensors was tested using cyclic voltammetry 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 respectively. A detailed description of the methodology used is provided below.

In this study plasma-assisted nitrogen doping of a CuOeNiO mixed oxide thin film was presented. The as prepared film was also applied as a glucose sensor. The nitrogen species generated during plasma ignition resulted in a beneficial phase transformation of CuO to Cu 2 O. Characterisation techniques such as XRD, SEM, EIS and Hall Effect etc. measurements were utilized to study the morphology, structural features, doping profile and electrical properties of the sensing material. Device performance electrochemical testing showed that the as-developed sensor (labelled as NeCuO/Cu 2 O:NiO) showed an ultrafast response time of 2.5 s with high sensitivity (1131 mA/mM.cm 2 ). The linear range of the sensor was calculated to be up to 2.74 mM of glucose and excellent selectivity towards glucose at an applied potential of þ0.67 V vs Ag/AgCl in 0.1 M NaOH electrolyte solution. The limit of detection was calculated to be 20 mM for the NeCuO/Cu 2 O:NiO sensor. The NeCuO/Cu 2 O:NiO have smaller Tafel slope compared to pristine CuO and CuO:NiO mixed oxides. Enhanced electrochemical performance of the NeCuO/Cu 2 O:-NiO originates from the improved electronic properties of the thin film.

“…The characteristic peaks of carbon cloth appear at 38.3°, 44.6°, 66.9°, and wide peaks at 22.6° and 25.7°, as shown by curve b in Figure (B). The diffraction peak of MOF (curve c) appears near 14.8°, 20° and 24.9°, assigned to the crystalline planes of (011), (020) and (200) . It can be seen from the curve d in Figure (B) that PANI/Ni‐MOF@CC showed the characteristic peaks of PANI at 20° and 24.9°, the features of CC at 38.3°, 44.6° and 66.9° and those of Ni‐MOF near 14.8°, 20° and 24.9°, which prove that Ni‐MOF, PANI and CC are successfully combined together.…”

In this work, the nickel‐based metal organic framework (Ni‐MOF) is attached to the conductive carbon cloth (CC) by using a hydrothermal reaction. In order to make MOFs strongly interacted with CC, polymeric molecules of polyaniline (PANI) are deposited on Ni‐MOF@CC employing an in–situ polymerization method. The PANI shows a three‐dimensional fiber‐network morphology. Due to the improved electrical conductivity and the porous networks, the electrochemistry property of the obtained flexible PANI/Ni‐MOF@CC is greatly enhanced compared with Ni‐MOF@CC. The specific capacitance of PANI/Ni‐MOF@CC reaches 109 F cm−2 (573 F g−1). The optimum energy density of PANI/Ni‐MOF@CC at 0.1 A cm−2 can be 7 mWh cm−2 with power density of 70 mW cm−2. Because the fiber networks of PANI on MOF enhances the interactions between MOF and CC, the PANI/Ni‐MOF@CC shows high stability of 95 % capacitance retention after 5000 charge‐discharge cycling.
