“…In order to overcome these issues, enzyme-free sensors have been designed with modified materials towards the goal of minimizing the drawbacks of traditional enzymatic sensors [13]. Recently, metal oxide materials such as Co [14], Ni [15], Fe [16], Cu [17] and Mn [18] have been used in sensor applications due to their attractive dominant properties including large surface area, long-term stability, catalytic efficiency and excellent conductivity [19]. Also, their metal oxide composite materials outstandingly enhance the electrochemical performances of the sensor [20].…”

A novel composite material of copper (I) oxide at manganese (IV) oxide (Cu 2 O@MnO 2 ), was synthesized and applied for modification on the glassy carbon electrode (GCE) surface (Cu 2 O@MnO 2 /GCE) as a hydrogen peroxide (H 2 O 2 ) sensor. The composite material was characterized regarding its structural and morphological properties, using field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The Cu 2 O@MnO 2 /GCE showed an excellent electrocatalytic response to the oxidation of H 2 O 2 which provided a 0.56 s À1 charge transfer rate constant (K s ), 1.65 3 10 À5 cm 2 s À1 diffusion coefficient value (D), 0.12 mm 2 electroactive surface area (A e ) and 1.04 3 10 À8 mol cm À2 surface concentration (g). At the optimal condition, the constructed sensor exhibited a wide linear range from 0.5 mM to 20 mM with a low limit of detection (63 nM, (S/N = 3) and a good sensitivity of 256.33 mA mM À1 cm À2 . It also presented high stability (DI response AE 15 %, n = 100), repeatability (1.25 %RSD, n = 10) and reproducibility (3.55 %RSD, n = 10). The results indicated that the synthesized Cu 2 O@MnO 2 was successfully used as a new platform for H 2 O 2 sensing.

Nickel oxide (NiO) has emerged as one of the most promising transition-metal oxides (TMOs) for electrochemical capacitors, batteries, catalysis, and electrochromic films, owing to its cost-effectiveness, abundance, and well-defined electrochemical properties. Recent studies have identified that mixing NiO with graphene or graphene derivatives results in novel composites with synergistic effects and superior electrochemical performance. This review summarizes the latest advances in composites of NiO with graphene or graphene derivatives. The synthetic strategies, morphologies, and electrochemical performance of these composites are introduced, as well as their electrochemical applications in supercapacitors, batteries, sensors, catalysis, and so forth. Finally, tentative conclusions and assessments regarding the opportunities and challenges for the future development of these composites and other TMOs/graphene or graphene-derived composites are presented.

“…To make the NiO sensor employed in practical application, great efforts have been devoted to the improvement of its electrochemical performance. [18][19][20] Nevertheless, limited by the inherently poor electronic conductivity and large volume changes, the design of NiO as a high-efficiency sensor mainly focuses on optimizing the nanoarchitectures to enhance the electrochemical reactivity. Due to the crosslinking texture with large surface area and rational porous structure, hierarchical porous nanomaterials, which are assembled by low-dimensional nanostructured blocks, represent the enhanced electronic conductivity, increased active sites and facilitated mass-transfer ability.…”

Exploring the sensitive and reliable methods for the determination of hydrogen peroxide (H 2 O 2 ) is a crucial issue for the health and environmental challenges. Herein, we demonstrate a facile, but rational and effective solvothermal approach to the synthesis of hierarchical NiO mesoporous nanospheres (NiO-MNS) as an effective non-enzymatic sensor towards the H 2 O 2 detection. Owing to the intercalation and stabilization effect of polyethylene glycol for the Ni(OH) 2 intermediate, the NiO mesoporous nanosphere (NiO-MNS) product is consistent with the low-dimensional nanostructured NiO blocks with large surface area and plentiful mesopores after the calcination treatment. The obtained NiO-MNS sensor presents superior electrochemical performance with a high sensitivity (236.7 mA mM À1 cm À2 ) and low limit of detection (0.62 mM), as well as the good selectivity and reliability for the further application of H 2 O 2 detection. In addition, the unraveling mechanism of the mesopores formation derived from the in situ measurements also offers the valuable guidance for the future design of porous materials for electrochemical devices and other applications.
