The structural feature of Ni–Al-LDH nanosheets and their adsorption performance for ethyl mercaptan from methane gas

Abstract

The adsorption of ethyl mercaptan (EM) on Ni–Al layered double hydroxide nanosheets (Ni–Al-LDH-NS) was investigated by an adsorption experiment on a fixed bed adsorption apparatus and density functional theory calculations (DFT).

Superhydrophobic and superlipophilic LDH flower balls/cellulose membranes for efficient oil–water separation

“…The diffraction peaks at 11.3°, 22.8°, 34.6°, 39.0°, 46.2°, 60.2° and 61.5° are assigned to the (003), (006), (012), (015), (018), (110) and (113) planes, respectively, and are in accordance with the standard (JCPDS 15-0087). 30,31 In addition, the sharp diffraction peaks reveal the high crystallinity of LDH nanosheets formed in the water phase.…”

2D layered double hydroxides and transition metal dichalcogenides for applications in the electrochemical production of renewable hydrogen

“…60 However, the formation of 2D LDHs is more challenging as these layers are held by strong electrostatic interactions. A number of exfoliation approaches have been successfully employed to give 2D LDHs nanosheets and these include solvent systems such as deep eutectic solvents, 61 organic solvents such as formamide, 62,63 and formamide with NH 4 NO 3 where the ammonium salt serves to increase the interlayer spacing. 62 Ethanol has also been used following pre-treatment of the as-synthesised LDH in a sodium acetate solution.…”
