Stabilizing the Fe Species of Nickel-Iron Double Hydroxide via Chelating Asymmetric Aldehyde-Containing THB Ligand for Long-Lasting Water Oxidation.

Nickel-iron layered double hydroxides (NiFe LDHs) are considered as promising substitutes for precious metals in oxygen evolution reaction (OER). However, most of the reported NiFe LDHs suffer from poor long-term stability because of the Fe loss during OER resulting in severe inactivation. Herein, a dynamically stable chelating interface through in situ transformation of asymmetric aldehyde-ligand (THB, 1,3,5-Tris(3'-hydroxy-4'-formylphenyl)-benzene) modified NiFe LDHs to anchor Fe and significantly enhance the OER stability is reported.

Interfacial Confinement Effect of Self-Adsorbed Monolayer Enables Highly Reversible Zn Metal Anodes.

The practical applications of aqueous Zn metal batteries are promising, yet still impeded by the corrosion reactions and dendrite growth on the Zn metal anode. Here, a self-adsorbed monolayer (SAM) is designed to stabilize the Zn metal anode. Theory and experiment results show that the interfacial confinement effect of the SAM, for one thing, greatly suppresses the corrosion reactions through the HO-poor inner Helmholtz plane because of the steric-hindrance effect, and for another, alleviates the Zn concentration gradient on the anode surface through the Zn enrichment behavior and eventually inhibits the dendrite growth.
