Deep eutectic solvents regulation synthesis of multi-metal oxalate for electrocatalytic oxygen evolution reaction and supercapacitor applications

Investigation of polyethylene glycol (PEG) assisted solvothermal synthesis of CuCoO2 nanosheets for efficient oxygen evolution reaction

“…Because the long chain structure of PEG formed a space constraint, this led to the formation of a sheet structure. 29,30 By decreasing the PEG addition from 50 to 10 mL, the intensity of the XRD peak belonging to the Co 3 O 4 impurity became much weaker. When the amount of PEG added was 30 mL, the synthesized CuCoO 2 appears as uniform hexagonal nanosheets with a thickness of 15 nm, and a size of about 150 nm (Fig.…”

Recycling spent LiNi1−x−yCoxMnyO2 cathodes to efficient catalysts for the oxygen evolution reaction

“…A broad peak at 3480 cm −1 corresponding to stretch vibrations of the O-H bond in CHCL for CA-CHCL-EG exhibits a significantly more comprehensive profile than that of CA-CHCL, indicating the successful formation and preservation of the hydrogen bonding network. 26,27 After the extraction of metal ions, the -COOH bond in CA shifted to 1728 cm −1 , indicating the complexation between the metal ion and the -COOH bond. 28 The formation of hydrogen bonding and the complexation of metal ions with citric acid is conducive to the formation of assembled rod-like shapes.…”

Ionic Liquid/Deep Eutectic Solvent-Mediated Ni-Based Catalysts and Their Application in Water Splitting Electrocatalysis

“…It indicated that DES-derived Ni-Fe alloy was a high-performance and stable electrocatalyst for water splitting. Yang et al applied DESs (polyethylene glycol-critic acid (PEG-CA) DES, PEG-oxalic acid (PEG-OA) DES, and EG-CA DES to synthesize multi-metal oxalate consisting of Fe, Co, Ni, Cu, and Zn [70]. It was found that the structure and composition of DESs could control the nucleation and growth of multi-metal oxalate.…”
