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.

Utilizing subphthalocyanine (SubPc) and 4,4 0 -dihydroxybiphenyl (C 12 H 10 O 2 ) as the raw materials, an innovative axial substituted SubPc H 12 SubPcB-OPh 2 OH was synthesized by solvothermal method. The density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations were employed to further study the properties and structures of H 12 SubPcB-OPh 2 OH. To expand photocatalytic activities for organic dyes degradation, H 12 SubPcB-OPh 2 OH was decorated onto surface of TiO 2 nanoparticles to fabricate high-efficiency H 12 SubPcB-OPh 2 OH/TiO 2 photosensitive catalysts. The degradation experiments indicated that the H 12 SubPcB-OPh 2 OH/TiO 2 catalyst with the mass ratio of 1:25 had the greatest performance in the elimination of methyl orange (MO), bromophenol blue (BB), methylene blue (MB), and acid fuchsin (AF). The 29.4%, 72.5%, 27.6%, and 64.8% of MO, BB, MB, and AF was removed by pure TiO 2 in 180-min, respectively. Under the same conditions, the photocatalytic rate of H 12 SubPcB-OPh 2 OH/TiO 2 can reach 96.3%, 99.5%, 97.5%, and 99.5%, separately. The efficiency of the as-synthesized composite was 3.3, 1.4, 3.5, and 1.5 times higher than that over bare TiO 2 for MO, BB, MB, and AF degradation under visiblelight irradiation, respectively. Besides, after five cycles of experiments, the degradation rate of H 12 SubPcB-OPh 2 OH/TiO 2 photocatalyst to BB can still reach 90.2%, which demonstrated that the obtained photocatalysts possessed remarkable stability and is much higher than 15.6% of pure TiO 2 . This study provides a new idea to the construction of photosensitive catalysts based on TiO 2 for water purification.

Energy storage technology plays a critical role in integrating variable energy sources into the grid and ensuring energy consistency. Electrochemical supercapacitors are one of the most promising energy storage devices, as they present multiple advantages of high power density, rapid charge/discharge characteristics, and long‐term cycle stability. Herein, the NiCo2O4/molybdate nanocomposites are developed as electrode materials for supercapacitor applications. The NiCo2O4/molybdate nanocomposites are synthesized by a facile single‐pot hydrothermal method and are coated on a carbon cloth substrate to form flexible supercapacitor electrodes. The structures, chemical compositions, morphologies, and textural properties of these materials are carefully studied by X‐Ray diffraction, X‐Ray absorption spectroscopy, scanning electron microscopy/energy‐dispersive X‐Ray spectroscopy mapping, and N2 adsorption–desorption isotherms. The formation of spinel NiCo2O4 nanorods decorated with molybdate (AMoO4, A = Co, Ni) particles is confirmed for all samples. The NiCo2O4/CoMoO4 electrode exhibits pseudocapacitive behavior and provides the highest specific capacitance (287.28 F g−1 at current density 6 A g−1), about 5.5 times as high as that of NiCo2O4, with excellent cycle stability (107% specific capacitance retention after 1000 charge/discharge cycles at 1 A g−1). Therefore, the NiCo2O4/CoMoO4 composites can be considered as a promising pseudocapacitor electrode material.
