“…Similar type of results was also obtained in UV-exposed CdSiO 3 :Dy 3+ (1-9 mol%) nanophosphor [18]. Some authors [19] studied crystallanity, phase and morphology of CdSiO 3 :Co 2+ (1-7 mol%) nanophosphor prepared by low temperature solution combustion method using different fluxes (NaF, NaCl, NH 4 F and NH 4 Cl). TL glow curves of CdSiO 3 :Co 2+ with different fluxes was studied for 10 min UV-exposure.…”

“…Previous studies have also reported similar characteristics for solution combustion synthesis. 30,31 Therefore, these findings demonstrate the importance of selecting an appropriate fuel to achieve the desired morphology and porosity of the synthesized material. The above discussion further indicates that out of the fuels studied only urea gives a well defined morphology.…”

In this study, we report the synthesis of Nickel Cobalt Oxide (NiCoO2) nanoparticles by the solution combustion method using Citric acid, Glycine, Urea, and Glucose as green fuels, for the electrochemical detection of 4-nitrophenol (4-NP) is reported. The synthesized NiCoO2 nanoparticles were characterized using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDAX). It was found from XRD and SEM, that the NiCoO2 synthesized using urea as a fuel had smallest crystalline size and promising morphology and hence this sample was used for electrochemical studies. Cyclic Voltammetry (CV) was employed to investigate the electrochemical behaviour of the synthesized NiCoO2 nanoparticles towards 4-Nitrophenol (4-NP) detection. It was found that the NiCoO2 nanoparticles exhibited a strong electrochemical response towards the detection of 4-NP, with a linear range of 10-100 µL and the lowest detection limit of 6.83nM. Overall, the NiCoO2 nanoparticles synthesized using the solution combustion method show an excellent potential for the detection of hazardous 4-NP, which could be applied in environmental sensing applications.

“…The FESEM image of the product obtained from F/O = 4 is completely agglomerated with well‐defined particle sizes and shapes. This change in the morphology of the Co 3 O 4 with an increase in the F/O ratio is due to a change in the exothermicity and quantity of gasses produced during the solution combustion reaction [25, 26, 39, 40]. It is a general trend that, with an increase in the F/O ratio, the product is expected to contain traces of unburnt carbon in the elemental form.…”

In this study, the authors present a morphology-controlled synthesis strategy for the preparation of Co 3 O 4 nanoparticles. The importance of the fuel (ascorbic acid) to oxidiser (cobalt nitrate) ratio (F/O ratio) in obtaining evenly distributed nanoscale grain Co 3 O 4 with pure crystalline phases using the solution combustion method is proposed. The structural features of all the as-formed cobalt oxide nanoparticles were studied using the powder X-ray diffraction technique, a field emission scanning electron microscope and Raman spectroscopic techniques. The electrochemical characteristics of all the as-formed cobalt oxide nanoparticle-embedded electrodes were examined by cyclic voltammetry, galvanostatic charge-discharge studies and electrochemical impedance spectroscopy in a 2 M KOH solution. The electrochemical data demonstrated that the Co 3 O 4 nanoparticles showed good capacitive behaviour. The morphological changes in the Co 3 O 4 nanoparticles affect the charge storage mechanism, and Co 3 O 4 nanoparticles with an F/O ratio equal to 1 (COO2)showed the highest electrochemical property, with a specific capacitance of 166 F g −1 at a current density 0.5 A g −1 . The COO2 electrode material showed capacitance retention of 90% after 5000 cycles.
