One-step spontaneous growth of NiFe layered double hydroxide at room temperature for seawater oxygen evolution

Efficient Alkaline Water/Seawater Hydrogen Evolution by a Nanorod‐Nanoparticle‐Structured Ni‐MoN Catalyst with Fast Water‐Dissociation Kinetics

“…[ 7 ] For example, the chlorine evolution reaction (ClER) from chloride ions (Cl − , ≈0.5 m ) in the seawater might compete with the oxygen evolution reaction (OER) on the anode and thus lower the overall seawater‐electrolysis efficiency. [ 6a,b,8 ] Catalyst corrosion by chloride ions and poisoning by insoluble precipitates (dust, colloids, and bacteria) will degrade catalytic activity and durability. [ 3b,6b,9 ] Some recent works point out that corrosion‐resistant electrolyzers and affordable membranes play important roles in direct seawater electrolysis, which can affect the device lifetime and efficiency of the system.…”

Amorphous–crystalline FeNi2S4@NiFe–LDH nanograsses with molten salt as an industrially promising electrocatalyst for oxygen evolution

“…16 Transition metal layered double hydroxides (TM-LDHs) such as NiFe-LDH, NiCo-LDH, NiMn-LDH and NiV-LDH with proper M-O bond energy and a special two-dimensional nanosheet structure are considered as the most potential OER catalysts in alkaline media. 24,25 Among them, NiFe-LDH possesses a unique 3d electronic structure to facilitate bonding with OER intermediates, holding great promise for industrial applications. 26,27 According to a literature report, amorphous materials with inherent disorder and defect sites can significantly increase the number of active sites for excellent catalytic performance.…”

CdS nanocages@defective-CoNi-LDH with bilayer porous hollow frameworks toward optimized sono-photocatalytic performance

“…Inspired by the sound absorption shown by honeycomb structures, CdS was used as a catalyst and structurally tunable LDH as a cocatalyst to synthesize CdS@LDH composites; LDH has a hollow porous skeleton and provides a large specic surface area with which to form a Zscheme heterogeneous structure for CdS and introduce metal vacancy defects during the synthetic process to greatly improve the photocatalytic performance of hydrotalcite. [21][22][23][24] Here, we synthesized CdS nanocubes via two controlled suldation to compare the sono-photocatalytic performance observed with different degrees of hollowness, and then MOF templates were used to etch complex hollow porous LDH nanocages with controlled defects via reactions with metal salts. This double-layer cladding structure acted as a nanoreactor for fast photocatalytic reactions.…”
