Transition metal oxides with two different cations in the same crystal structure are considered to perform better as catalysts due to the synergistic effects causing better charge transfer and the availability of more active sites. Chemicals with molybdate anion (MoO4−) have been proven to have vast industrial importance in arenas like catalysis, supercapacitance, nuclear medicine, calorimetry, etc. In particular, nanostructured nickel molybdate (NiMoO4) is a promising entrant as an electrode substance for sophisticated power bank applications, apart from being a catalyst for chemical reactions involving energy conversion. Engineering of NiMoO4 at different scopes has been proven to cause a vast enhancement in the catalytic performance of nanometric NiMoO4 through improvement in redox reaction kinetics during the last couple of decades. This review imparts a precise thought about NiMoO4 considering all its developments in the unearthing of properties, synthesis routes, and analyzing tunability for improvement in attributes towards focused applications.

“…Compared with the other two types of materials, battery-type materials have higher capacity and energy density for the fast redox reactions on the surface coupled with those in the bulk, and they have accordingly become the focus of research. Currently, battery-type materials are mainly transition metal-based compounds, such as Co 3 O 4 , , Ni(OH) 2 , , NiMoO 4 , , NiCo 2 O 4 , , and NiCo 2 S 4 . , Among these candidates, NiMoO 4 and NiCo 2 O 4 have aroused much attention because of their high theoretical capacity, adjustable morphology, and low cost. − Despite the fact that NiMoO 4 and NiCo 2 O 4 have achieved remarkable development in recent years, there is still a huge gap between the actual capacity and theoretical capacity caused by the low electronic conductivity. − Besides, the unsatisfied cycling stability and rate performance further limit the application of battery-type materials in supercapacitors.…”

Hierarchical structure design of transition metal compounds is a promising method for improving the electrochemical properties of supercapacitors. In this work, a 3D electrode is obtained by in situ growing of NiMoO4@NiCo2O4 core–shell nanorods on Ni foam (NF) followed by an annealing process (NF@NiMoO4@NiCo2O4). The hierarchical structure with ordered pores on a surface enables a uniform charge distribution, provides effective electron/ion transfer channels, and maintains structural integrity over long periods of cycling, which collectively results in excellent electrochemical properties with an extraordinary specific capacitance of 1920 F g–1 at 1 A g–1 as well as 91.6% capacitance retention after 10 000 cycles. Furthermore, a flexible solid-state asymmetric supercapacitor fabricated with NF@NiMoO4@NiCo2O4 achieves a superior energy density of 54.5 Wh kg–1 (at 845 W kg–1) and an outstanding cycling stability with 83% capacity retention over 10 000 cycles. The hierarchical 3D electrode design in this work will contribute to the development of high-performance supercapacitors and shows promising prospects in flexible and portable energy storage systems.

The design and development of effective electrocatalysts containing nonprecious materials for oxygen evolution reaction (OER) in seawater splitting remains a significant challenge for large‐scale industrial hydrogen production. Nonprecious bimetallic oxide‐constructed catalysts are utmost promising candidates to obtain boosting electrochemical water oxidation performance. Herein, a transition bimetallic oxide nanostructure electrocatalyst as NiMoO4 vertically standing nanosheet over the nickel foam substrate (NiMoO4/NF) for electrochemical water oxidation process in alkaline fresh/simulated seawater conditions is presented. NiMoO4 nanostructure on NF substrate is successfully obtained using a straightforward hydrothermal reaction route and thermal annealing processes. The surface morphology with elemental characteristics of the resultant NiMoO4/NF sample exposes highly homogenous vertical standing nanosheets assembled on the NF surface. The electrochemical water oxidation performance of the as‐prepared electrodes demonstrates the function of diverse hydrothermal reaction times (3, 6, and 9 h) in fresh and simulated seawater electrolyte conditions. In alkaline seawater electrolyte conditions, optimal hydrothermal reaction time‐assisted NiMoO4/NF‐6 h electrocatalyst possesses significant OER electrocatalytic actives compared to the other samples. Similarly, NiMoO4/NF‐6 h catalyst exhibits a small overpotential of 429 mV to achieve a current density of 50 mA cm−2 with a Tafel slope value of 122 mV dec−1 for OER process. As a result, the resultant superior electrocatalytic performance of the optimal hydrothermal reaction time‐aided electrocatalyst (NiMoO4/NF‐6 h) is ascribed to highly accessible catalytic active centers and enhanced charge transfer kinetics at the interface for electrochemical reactions. Thus, proposed nanostructure‐constructed electrocatalysts could prove to be prospective OER candidates for electrochemical water oxidation.
