A three electrode electrodeposition method is used for the synthesis of Ni@Co–Fe LDH nanowires in two phases: first the deposition of Ni nanowires (core) and second is the deposition of Co–Fe LDH (shell) as shown in figure 1. Before deposition, polycarbonate membrane used as template was cleaned ultrasonically in an ultrasonic …

Fabrication of Ramie@LDH LDHs modified ramie fabrics (Ramie@ LDH) were prepared through a hydrothermal process. Ni (NO 3) 2 ·6H 2 O (1.28 g), Fe (NO 3) 3 ·9H 2 O (0.91 g) and urea (4.50 g) were blended uniformly in 180 mL of deionized water, and the mixture was poured to a Teflon-lined stainless steel autoclave.

The morphology of LDH array also changed with the increasing of Co 2+ /Al 3+ ratio, which was regulated by alting the concentration of Co 2+ at the concentration of Al 3+ was 0.01 mol/L and hydrothermal reaction time was 10 h. With the increase of Co 2+ /Al 3+ ratio, more substrate surface was covered with the vertical array, as shown in Fig. …

Herein, we present the synthesis of well-aligned vertical Ni@Co–Fe LDH core–shell nanowires and Ni(OH) 2 nanowires as negative and positive supercapacitor electrodes using polycarbonate membrane via three electrode electrochemical deposition on a flexible copper substrate and then characterize it for energy storage. An asymmetrical ...

Synthesis of Co-Co LDH/TNS: Different quality (8 mg, 15 mg, 22 mg, 30 mg) TNS powder was sonicated in 15 mL methanol for 1 h. Subsequently, 0.546 g Co (NO 3) 2 ·6H 2 O was added into the above solution and stirred 2 h. Then, 0.616 g 2-MIM was dissolved in 15 mL methanol and mixed with the Co (NO 3) 2 /TNS solution.

The vertical LDH nanosheets are grown in-situ using an aqueous solution containing 150 mM Co (NO 3) 2 and 150 mM FeSO 4. The working electrode (Pt) is biased at -0.6V. Similarly, the lateral LDH nanosheets are grown in-situ when the concentration of the precursor solution is lowered, containing 15 mM Co (NO 3) 2 and 15 mM FeSO 4.

Here, we demonstrate a dramatic enhancement of HER kinetics in base by judiciously hybridizing vertical MoS2 sheets with another earth-abundant material, layered double hydroxide (LDH). The resultant MoS 2 /NiCo-LDH hybrid exhibits an extremely low HER overpotential of 78 mV at 10 mA/cm 2 and a low Tafel slope of 76.6 mV/dec in 1 M …

The Al-based LDHs was synthesized following Co-precipitation method by maintaining the molar ratio of divalent metal cations and trivalent Al +3 ion in 2:1 M ratio. The calculated amount of divalent M 2+ (Co +2, Ni +2, Mg +2) (No 3) 2 ·6H 2 O and trivalent Al (No 3) 3 ·9H 2 O was mixed together.

Layered double hydroxides (LDHs) are a class of lamellar materials with a wide range of potential catalytic applications. LDHs form from positively charged 2D atomic layers separated by charge-balancing anions and solvent molecules. Typically, nanoscale LDH sheets can grow vertical or parallel to a substrate, exposing their different active …
