“…Citric acid assisted combustion at 400 °C for 4 h resulted in highly porous NiCo 2 O 4 nanomaterials [ 191 ]. Urea-assisted combustion was processed at 400 °C for 2 h in ethyl acetate as a solvent [ 192 ]. In each case, a viscous gel is obtained initially by heating the reaction solution at low temperature followed by auto-ignition resulting in the formation of highly fluffy mass which is finally calcined at high temperature.…”

Non-enzymatic biosensors based on mixed transition metal oxides are deemed as the most promising devices due to their high sensitivity, selectivity, wide concentration range, low detection limits, and excellent recyclability. Spinel NiCo2O4 mixed oxides have drawn considerable attention recently due to their outstanding advantages including large specific surface area, high permeability, short electron, and ion diffusion pathways. Because of the rapid development of non-enzyme biosensors, the current state of methods for synthesis of pure and composite/hybrid NiCo2O4 materials and their subsequent electrochemical biosensing applications are systematically and comprehensively reviewed herein. Comparative analysis reveals better electrochemical sensing of bioanalytes by one-dimensional and two-dimensional NiCo2O4 nano-/microstructures than other morphologies. Better biosensing efficiency of NiCo2O4 as compared to corresponding individual metal oxides, viz. NiO and Co3O4, is attributed to the close intrinsic-state redox couples of Ni3+/Ni2+ (0.58 V/0.49 V) and Co3+/Co2+ (0.53 V/0.51 V). Biosensing performance of NiCo2O4 is also significantly improved by making the composites of NiCo2O4 with conducting carbonaceous materials like graphene, reduced graphene oxide, carbon nanotubes (single and multi-walled), carbon nanofibers; conducting polymers like polypyrrole (PPy), polyaniline (PANI); metal oxides NiO, Co3O4, SnO2, MnO2; and metals like Au, Pd, etc. Various factors affecting the morphologies and biosensing parameters of the nano-/micro-structured NiCo2O4 are also highlighted. Finally, some drawbacks and future perspectives related to this promising field are outlined.

“…ZnMn2O4 used as the spacer in the aerogel structure can prevent the agglomeration and re-stacking of rGO sheets while increasing the surface area. [8][9][10][11][12] Owing to their flexibility, high conductivity, and simple synthetic process, PANI and PPy are used to improve the working performance of SCs. It has been reported that PANI or PPy have been synthesized separately and used as components to make the hybrid aerogel with rGO.…”

“…There are many publications related to the research on the coupling of two semiconductor metal oxides to form a ternary metal oxide which can enhance the specific capacitance and electrochemical performance of SCs. [8][9][10][11][12][13][14][15][16] Among various kinds of ternary metal oxides, ZnMn2O4 appears to have great potential due to its advantages in magnetic, photocatalytic, and electrochemical performance. 17 In 2018, the application of carbon-coated ZnMn2O4 nanocrystallite SCs that exhibited the specific capacitance of 150 F/ g in Na2SO4 electrolyte was reported by Abdollahi-far et al 18 This study illustrated that the combination of ternary metal oxides and carbon-based materials could exhibit good electrochemical performance when used as the electrode for a SC.…”

Conductive polymers, such as polyaniline (PANI) and polypyrrole (PPy), are widely used in the design of supercapacitors because of their high pseudocapacitive performance as well as facile synthesis and low cost. In this study, hybrid aerogels based on reduced graphene oxide and ZnMn2O4 were modified by PANI and PPy. The 3D structure of the hybrid aerogels was obtained by using a one-step hydrothermal co-assembly method. Then, aniline and pyrrole were polymerized on and within the structure of the hybrid aerogel through in situ polymerization. The electrochemical properties of the hybrid aerogels were studied via cyclic voltammetry and galvanostatic charge-discharge testing to identify the effects of conductive polymers on the electrochemical properties of materials. It has been established that PANI and PPy facilitate an increase of the specific capacitance of rGO/ZnMn2O4 aerogels up to 297.8 F/ g and 108.24 F/g at 0.2 A/g scan rate, respectively.

There is a growing interest in supercapacitors as energy storage systems due to their high specific power, fast charge/discharge rates, and long cycling stability. Researchers have focused recently on developing nanomaterials to enhance the capacitive performance of supercapacitors. The inclusion of electroactive components, such as transition metal oxides (TMOs), carbonbased materials, and conducting polymers (CPs), is believed to play an important role in improving the electrochemical behavior of the electrode materials. Nevertheless, supercapacitors containing TMOs, carbon-based materials, and CPs commonly suffer from inferior ion-transport kinetics and poor electronic conductivity, which can affect the rate capability and cycling stability of the electrodes. Therefore, the development of TMO/CP and TMO/carbon-based electrode materials has gained widespread attention because they synergistically combine the advantages of both materials, enabling revolutionary applications in the electrochemical field. In general, TMOs have given good performance as electrodes for supercapacitors by further increasing the performance of the electrode when two metal cations are introduced into a single crystal structure. This Review describes and highlights recent progress in the development of bimetallic oxides regarding their design approach, configurations, and electrochemical properties for supercapacitor applications, at the same time providing new opportunities for future energy storage technologies.
