“…Thus, the CoeCu/Cu films electrodeposited at 6, 9 and 12 T magnetic field were characterized as non-magnetic materials. The presented results are in agreement with the compositional dependence of saturation magnetization and coercive field given by Karaagac et al [11,37]. The authors presented the EDX results, which have shown that both magnetization and coercivity are strongly affected by increasing amount of non-magnetic Cu component in the film.…”

“…It well known that the 3D porous foliage structure not only could accelerate the transport of the electrolyte, but also could provide a greater specific surface area in contacting with the analytes. Therefore, the 3D porous leaf‐like CuO‐CoNSs might be better for glucose sensing . As a contrast, the SEM image of CuO‐CoNSs/3D‐KSC was also provided in (Figure S3, Supporting Information).…”

A novel three‐dimensional kenaf‐stem‐derived macroporous carbon (3D‐KSC)/reduced graphene oxides (rGO) integrated electrode was constructed as a supporting matrix to deposit CuO−Co bimetallic nanostructures (CuO‐CoNSs) for electrochemical sensing of glucose. The rGO and CuO‐CoNSs were firmly grown on the channels of 3D‐KSC step‐by‐step to construct the CuO‐CoNSs/rGO/3D‐KSC integrated electrode. The obtained CuO‐CoNSs/rGO/3D‐KSC integrated electrode was carefully characterized with several techniques, such as SEM, Raman spectroscopy, FTIR, XRD, XPS, and electrochemistry. The results showed that lots of rGO covered the macropores of 3D‐KSC, which avoided the aggregation of rGO effectively and improved the utilization efficiency of 3D‐KSC. A large number of dendritic CuO‐CoNSs were subsequently grown in the macropores of the rGO/3D‐KSC integrated electrode. Owing to the hierarchical configuration, the CuO‐CoNSs/rGO/3D‐KSC integrated electrode showed superior performances for non‐enzymatic electrochemical glucose sensing with a suitable linear range (0.01–3.95 mM) and high sensitivity of 802.86 μA mM−1 cm−2. The result demonstrated that the electrode was suitable for detecting glucose in bodily fluids. The rGO/3D‐KSC might also be applied to load other NSs or enzymes for electrochemical sensing.

“…The deposition of Cu−Co bimetal nanoparticles on PEDOT/CNTs led to the formation of a coralloid‐like structure (Figure D). The nucleation of Cu−Co might be accelerated in the coexistence of bimetal and accordingly resulted in the formation of the coralloid microstructure of Cu−Co/PEDOT/CNTs. It was noticeable that Cu−Co directly deposited on the GCE was amorphous and irregular (Figure E).…”

Copper-cobalt bimetal nanoparticles (Cu-Co) have been electrochemically prepared on glassy carbon electrodes (GCEs), which were electrodeposited with conducting polymer nanocomposites of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with carbon nanotubes (CNTs). Owing to their good conductivity, high mechanical strength, and large surface area, the PEDOT/CNTs composites offered excellent substrates for the electrochemical deposition of Cu-Co nanoparticles. As a result of their nanostructure and the synergic effect between Cu and Co, the Cu-Co/PEDOT/CNTs composites exhibited significantly enhanced catalytic activity towards the electrochemical oxidation of nitrite. Under optimized conditions, the nanocomposite-modified electrodes had a fast response time within 2 s and a linear range from 0.5 to 430 μm for the detection of nitrite, with a detection limit of 60 nm. Moreover, the Cu-Co/PEDOT/CNTs composites were highly stable, and the prepared nitrite sensors could retain more than 96 % of their initial response after 30 days.
