Role of polymeric surfactant in the synthesis of cobalt molybdate nanospheres for hybrid capacitor applications

Tuning the Redox Properties of the Nanostructured CoMoO4 Electrode: Effects of Surfactant Content and Synthesis Temperature

“…To the best of our knowledge, the use of novel Pluronic F127 surfactant and the effect of the synthesis temperature and its physicochemical properties have not been reported. However, a preliminary study on F127 surfactant in CoMoO 4 has been reported in one of our earlier publications . The significance and novelty of the current study lies in understanding the effects of the metal‐to‐surfactant ratio and the synthesis temperature, which both influence the change in morphology and enable the redox properties to be tuned, which collectively enhance the specific capacitance of CoMoO 4 relative to that reported for this material in the literature .…”

“…The cyclic voltammetry and galvanostatic charge–discharge studies of the composites were carried out using SP‐150, Bio‐Logic Science Instruments, in 2 m NaOH electrolyte at room temperature. The ionic conductivity of the aqueous solution is two orders of magnitude greater than that of organic electrolytes, which allows higher discharge rates and lower voltage drops due to electrolyte impedance as discussed in the Results and Discussion.…”

“…The ability to store energy is necessary because capturing a small percentage of the potential wind and solar energy could contribute significantly to meeting the world's electrical energy requirements. Much effort has been devoted to developing new electrode materials and enhance its performance to satisfy the new energy demand . At present, to meet these requirements, transition‐metal oxides and phosphates have been found to exhibit superior redox activity and thus a high storage capability can be obtained at a relatively low cost .…”

“…At present, to meet these requirements, transition‐metal oxides and phosphates have been found to exhibit superior redox activity and thus a high storage capability can be obtained at a relatively low cost . Transition‐metal oxides and phosphates have been well known in the field for over two decades, whereas molybdates have evolved only recently. Metal molybdates, AMoO 4 ‐type compounds (in which A is the divalent metal ion), are an interesting material owing to their potential application in many fields including energy storage.…”
