Interlayer Spacing Regulation of NiCo-LDH Nanosheets with Ultrahigh Specific Capacity for Battery-Type Supercapacitors

“…Compared to NaAc10-LDH, an additional diffraction peak observed at 38.4° indicates the presence of the β-Ni­(OH) 2 phase in LDH . According to Bragg’s equation, the calculated value of the (003) crystal plane spacing of LDH was d (003) = 0.8 nm, which showed that the interlayer was intercalated by water molecules, CO 3 2– and Cl – . − With the introduction of Ac – anions, it was obvious that the (003) and (006) peak diffraction angles of NaAc10-LDH were reduced compared to pristine LDH, proving that the interlayer spacing of NaAc10-LDH was significantly enhanced to 0.94 nm (2θ = 9.436°), which was larger than that of the NiCo-LDH previously reported in the literature. , The increased interlayer spacing was mainly due to the electrostatic balance between the acetate ligand in the interlayer space and the host laminate …”

Preparation of Ni(OH)2 nanoplatelet/electrospun carbon nanofiber hybrids for highly sensitive nonenzymatic glucose sensors

“…Ni(OH) 2 /ECF was synthesized using a microwave method with ECF as the substrate. 25,26 ECF lm was prepared by combining electrospinning and subsequent carbonization. The general preparation was as follows: electrospun nanobers were prepared using an electrospinning process performed in an electric eld of 100 kV m À1 , created by applying a 30 kV electrical potential to a 30 cm gap between the spinneret and collector.…”

Facile synthesis of Ni(OH)2nanoplates on nitrogen-doped carbon foam for nonenzymatic glucose sensors

“…The Ni(OH) 2 / NCF was prepared by utilizing NCF as a template assisted with the microwave method. 23 In a typical experiment, 2.79 g Ni(NO 3 ) 2 $6H 2 O and 2.88 g urea were dissolved in 200 mL distilled water and 20 mL ethanol in a 500 mL three-necked ask in a microwave reactor. Aer stirring for approximately 30 min, the exible NCF was carefully soaked in the solution followed by heating to 90 C for 20 min under microwave irradiation.…”

“…21,22 However, the practical applications of Ni(OH) 2 materials are severely hindered by their relatively poor conductivity. 23 For this reason, hybrid electrode materials with synergistically enhanced electrochemical performance can be achieved through conning Ni(OH) 2 materials within conductive carbon-based frameworks to construct hybrid nanostructures.…”
