“…The Raman peaks at 170.3, 195.0, and 655.5 cm −1 can be indexed to the active modes of Se−Se pair in the hexagonal NiCoSe 2 , in which the sharp peak at 195.0 cm −1 can be due to the stretching modes of Se−Se. 45,46 It is found that the characteristic modes of NiCoSe 2 vanished completely and a broad peak appeared at 546.6 cm −1 after the activation process, which can be due to the overlap peaks of the stretching modes of Ni and Co hydroxides and NiCo oxyhydroxides. 38,47 The above results demonstrate that the NiCoP−NiCoSe 2 film can be reconstructed into NiCo hydroxides coexisted with a small amount of NiCo oxyhydroxides by the electrochemical activation process.…”

In order to explore a new electrocatalyst (or its precursor) for oxygen evolution reaction (OER), much attention has recently been given to the alternative engineering strategy for fabricating a novel nanofilm electrode with high efficiency and long duration. We herein use a two-step electrodeposition method to prepare a series of nanofilm electrodes containing Ni, Co, P, and Se on carbon cloth. After a suitable electrochemical activation process through cyclic voltammetry, the resultant binder-free NiCoP−NiCoSe 2 nano-bilayer films are transformed from compact layer(s) to porous nanoparticle ones composed by NiCo hydroxides and a small amount of NiCo oxyhydroxides and thus exhibit a striking electrocatalytic activity (lower to 243 mV overpotential for 10 mA cm −2 ) and excellent stability (80 h) for OER. The rougher surface, well-suited electronic structure originated from the Ni/Co codoping and the rational integration of NiCoP and NiCoSe 2 are important factors for the excellent OER performance of the NiCoP−NiCoSe 2 film after the electrochemical activation process. In addition, the results on overall water splitting reveal that the NiCoP−NiCoSe 2 film is also promising in the practical application of energy conversion and storage.

We have demonstrated the synthesis of defect-rich Ni-doped MoSe2 nanoplates (NiMoSe2) and their application as an efficient electrocatalyst for enzymatic biofuel cells and electrochemical pseudocapacitors. In this study, a new type of interpretation is proposed that a defective surface facilitates the effective entrapment of enzymes (glucose oxidase (GOD), laccase) for biofuel cells and additional ion diffusion for Faradic charge–discharge reaction. The transmission electron microscopy and UV–vis spectroscopy techniques scrutinized the formation of defects/distortions and the resultant successful entrapment of enzymes. The performed electrochemical characterizations of enzyme-immobilized NiMoSe2/nickel foam (NF) bioanode (NiMoSe2/GOD/NF) and biocathode (NiMoSe2/laccase/NF) exhibited better direct charge conductive behavior at the interface of enzymes and electrode material. Herein, the assembled biofuel cells exhibited an open-circuit voltage (V OC = 0.6 V) and a short-circuit current density (J SC = 8.629 mA cm–2) with a maximum power density (P max) of 1.2 mW cm–2. For the electrochemical pseudocapacitor application, the proposed NiMoSe2/NF exhibited excellent specific capacitance (535.74 F g–1), with 86.7% rate performance. Finally, this work suggests new insights into both enzymatic biofuel cell and supercapacitor applications.

“…Additionally, Co 3 O 4 /NiCo 2 O 4 double-shelled nanocages provided sufficient mesopores and large specific surface area for improved H 2 O 2 sensing [ 290 ]. Sakthivel et al [ 291 ] compared the electrochemical kinetics of modified NiCo 2 O 4 /GCE, NiCo 2 S 4 /GCE, and NiCoSe 2 /GCE toward H 2 O 2 . The modified NiCoSe 2 /GCE showed better electrochemical sensing behavior for H 2 O 2 than modified NiCo 2 O 4 /GCE and NiCo 2 S 4 /GCE.…”

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.
