Facile synthesis of mesoporous CoFe mixed oxide from MOF as advanced electrode material for supercapacitor

Unprecedented Dual Role of Polyaniline for Enhanced Pseudocapacitance of Cobalt–Iron Layered Double Hydroxide

“…Compared with the pristine CoFe-LDH electrode, the optimized amount of PANI astonishingly upsurges the capacitance of the composite electrode by ≈49.4%. The CoFe-LDH/P2 electrode achieves a much broader potential window than all previously reported Co/Fe-based electrodes [47][48][49][50][51][52] and the highest specific capacitance among other electrodes due to the well-balanced amount of PANI and homogenous pores on the surface of CoFe-LDH. While the decreased performance of the CoFe-LDH/P3 is mainly due to the deprotonation effect of a high concentration of PANI in alkaline electrolyte.…”

Modular preparation of functional bimetallic spinels from metal–organic frameworks: a deep exploration from macro and micro perspectives

“…47 MnCo 2 O 4 synthesized using MIL-53 by Yao et al formed a special rod-like structure, 48 while MnCo 2 O 4 using the PBA prepared by Zhao et al had a standard cubic structure. 49 Nie et al synthesized CoFe 2 O 4 with a spindle shaped structure by using MIL(88A), 50 while Long et al synthesized CoFe 2 O 4 with a cubic structure by using hybrid metal hexacyanoferrate (h-MHCFs) (Fig. 2a).…”

“…Thanks to their excellent structural features, MOF-derived bimetallic spinels have been widely studied and applied in SCs (Table 4 summarizes in detail their application advantages in SCs). 50,147,148 with a layered nano-cage structure using ZIF as the precursor, and employed it as an active electrode material for SCs. 47 During the reaction, MnCo 2 O 4 achieved Faraday oxidation-reduction through reversible transformation between the oxidation state of Co ions (Co 2+ /Co 3+ /Co 4+ ) and Mn ions (Mn 2+ /Mn 3+ /Mn 4+ ), which could produce higher capacitance and energy density.…”
