Synthesis, characterization, and catalytic behaviour of nano-bimetallic nickel oxide on the thermal decomposition of dihydroxylammonium-5,5 0 -bistetrazole-1,1 0 -diolate)Bimetal combustion catalyst has become an emerging field in recent years, which is still in its infancy. When the combustion catalyst is used in double-base propellants, it can produce effects that conventional catalysts cannot achieve. In this study, nano-bimetallic nickel oxides (nanospheres of NiFe 2 O 4 and the sub-nanometre flower NiCo 2 O 4 ) were prepared by hydrothermal method and characterized using X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and N2 adsorption-desorption test (BET). Moreover, its thermal catalytic action on dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate (TKX-50) was studied. The thermal analysis of composite TKX-50/NiFe 2 O 4 and TKX-50/NiCo 2 O 4 was carried out by thermogravimetric differential scanning calorimetry (TG-DSC). The results show that when the addition amount of NiFe2O4 is 10%, the heating rate is 5.0 K min −1 , the NiFe 2 O 4 has the best catalytic activity for TKX-50 thermal decomposition, and the high thermal decomposition peak temperature (Tpeak1) is decreased by 29 °C. More interestingly, the apparent activation energies of the two composites were calculated by Kissinger, Ozawa, and Starink methods. The advanced thermal analysis kinetics software (AKTS) was used to perform kinetic calculations on the DSC experimental curves of the abovementioned composite energetic materials, and reaction rate curves obtained by the simulation are in good agreement with the experimental curves of the thermal decomposition reaction process, further proving that the accuracy of the experiment is high. Therefore, the addition of NiFe 2 O 4 shows high catalytic efficiency on the thermal decomposition of TKX-50 components, and this would be beneficial to promote the burning rate of propellants containing TKX-50 components.

“…The accomplished values are greater or even comparable to the recently reported Ni and Co materials based hybrid systems (Table S2). [41][42][43][44][45][46][47][48] Furthermore, the cyclic stability and Coulombic efficiency of the NCO1//AC HSC was investigated for continuous 20 000 GCD cycles at 10 A g À1 with almost 99% of the Coulombic efficiency (Figure 5H). It can be observed that the HSC retained around 80.56% of its initial capacitance maintained over 20 000 cycles, emphasizing the excellent stability and reversible behavior of the HSC.…”

Nickel cobalt oxide (NCO) is considered an auspicious electrode candidate for the reinforcement of energy-storage devices. Currently, an immense interest is devoted to modifying the morphological aspects of the NCO to boost their surface texture and electrochemical performances, which is feasible for the development of high energy density and durable devices. Herein, we report the synthesis of layered NCO nanosheets via solvothermal reaction by tuning the solvent volume ratio (water/N,N-Dimethylformamide [DMF]) for supercapacitor electrode material. The nickel cobalt oxide is prepared utilizing a 1:2 (DMF:water) ratio of solvent (NCO1) displays a controlled growth of 2D nanosheets with excellent surface texture. Moreover, NCO1 demonstrates the battery type charge storage properties with a maximum specific capacitance (C sp ) of 731 F g À1 , which is far better than NCO2 (623 F g À1 ) and NCO3 (556 F g À1 ) prepared in other solvent proportions. Besides, the constructed hybrid supercapacitor utilizing activated carbon (AC) and NCO1 as the negative and positive electrodes, respectively, exhibits the C sp of 120 F g À1 , and maximum specific energy 37.33 W h kg À1 for the specific power 691.31 W kg À1 and demonstrates excellent stability~80.56% for 20 000 cycles.In different electrochemical energy storage devices, supercapacitors (SCs) have gained abundant consideration as a novel and promising future energy storage device. [1][2][3] Due to their cost effectiveness, fast discharge and charge rate, extraordinary power density, exceptionally extended lifespan, and better safety reliability. [4][5][6] Despite SCs have these excellent features, the limited energy density has severely restricted their feasible application compare to batteries. 7-9 Thus, it is essential to lift

The purpose of this investigation was the development of a new colloidal route for the fabrication of Mn3O4 electrodes for supercapacitors with enhanced charge storage performance. Mn3O4-carbon nanotube electrodes were fabricated with record-high capacitances of 6.67 F cm−2 obtained from cyclic voltammetry tests at a scan rate of 2 mV s−1 and 7.55 F cm−2 obtained from the galvanostatic charge–discharge tests at a current density of 3 mA cm−2 in 0.5 M Na2SO4 electrolyte in a potential window of 0.9 V. The approach involves the use of murexide as a capping agent for the synthesis of Mn3O4 and a co-dispersant for Mn3O4 and carbon nanotubes. Good electrochemical performance of the electrode material was achieved at a high active mass loading of 40 mg cm−2 and was linked to a reduced agglomeration of Mn3O4 nanoparticles and efficient co-dispersion of Mn3O4 with carbon nanotubes. The mechanisms of murexide adsorption on Mn3O4 and carbon nanotube are discussed. With the proposed method, the time-consuming electrode activation procedure for Mn3O4 electrodes can be avoided. The approach developed in this investigation paves the way for the fabrication of advanced cathodes for asymmetric supercapacitors and multifunctional devices, combining capacitive, magnetic, and other functional properties.
