“…Previously, we used density functional theory (DFT) to investigate the growth mechanism of ferrous oxalate dihydrate and the influence of DEAc on its morphology, [20] and accumulated certain calculation experience. Therefore, the formation mechanism and morphology control mechanism of tubular ferrous oxalate will also be studied by density functional theory.…”

The formation mechanism and morphology regulation mechanism of tubular ferrous oxalate were investigated by density functional theory. The calculation results showed that the pH value of the reaction solution changed from slightly alkaline to acidic was an important condition for the formation of tubular ferrous oxalate. The size and dispersion of ferrous oxalate can be controlled by introducing Na + and ethylene glycol (EG) into the reaction system. Guided by theoretical calculations, using sodium oxalate as material to guarantee the initial solution to be slightly basic, while also introducing Na + . Regular tubular ferrous oxalate was successfully obtained by using different ratios of EG and H 2 O as reaction solution and adjusting pH values at different stages, verified the rationality of the theoretical calculation results. The tubular ferric oxide was obtained by thermal decomposition using tubular ferrous oxalate as the precursor, and the electrochemical performance test results showed that this material is a potential electrode material for supercapacitors.

“…Therefore, controlling the morphology and particle size of ferrous oxalate dihydrate are alternative ways to improve the material properties for further battery applications. The studies about morphology and particle size regulation of ferrous oxalate dihydrate show that adding surfactants has significant effect on the morphology and particle size of crystals [10–13] . The surfactant introduced into the reaction system affects the nucleation and crystal growth, resulting in different crystal structure, particle size and morphology, which further impacts the properties and applications of materials [14] …”

Surfactants containing hydroxyl functional groups have a significant influence on the morphology of ferrous oxalate dihydrate. However, few studies have provided a theoretical explanation for this effect. In this investigation, the size of ferrous oxalate dihydrate was reduced from micron to nanometer scale using anhydrous ethanol, and its mechanism was elucidated through density functional theory calculations. The calculational results reveal that anhydrous ethanol molecules bound to the ferrous oxalate dihydrate crystal via hydrogen bonding and van der Waals forces, thereby controlling crystal growth. It means that anhydrous ethanol molecules preferentially affected the interlayer interaction in the structure of ferrous oxalate dihydrate, leading to a significant impact on its overall crystal growth way. Furthermore, the electrochemical properties of ferrous oxalate dihydrate synthesized in aqueous and anhydrous ethanol systems were compared and tested. The specific capacitance (242 F ⋅ g−1 at 0.5 A ⋅ g−1 current density) of ferrous oxalate dihydrate synthesized in anhydrous ethanol system is obvious higher than that of ferrous oxalate dihydrate synthesized in water system (186 F ⋅ g−1), due to its smaller particle size (75 nm). Furthermore, the specific capacitance of this material can be improved to 469 F ⋅ g−1 during composite process of ferrous oxalate dihydrate with graphene oxide.
