Fast Kinetics Enabled by Ion Enrichment Layer for Dendrite-Free Zinc Anode.

Aqueous zinc-ion batteries (AZIBs) are considered a promising choice for energy storage devices owing to the excellent safety and favorable capacity of the Zn anode. However, the uncontrolled dendrite growth of Zn anode severely constrains the practical applications of AZIBs. Herein, a novel ion enrichment layer of CuS is designed and constructed on the Zn foil surface to achieve dendrite-free Zn anode.

Trimetallic MOF-derived Fe-Mn-Sn oxide heterostructure enabling exceptional catalytic degradation of organic pollutants.

Developing efficient and environmentally benign heterogeneous catalysts that activate peroxymonosulfate (PMS) for the degradation of persistent organic contaminants remains a challenge. Metal-organic frameworks (MOFs)-derived metal oxide catalysts in advanced oxidation processes (AOPs) have received considerable attention research fraternity. Herein, we report an innovative magnetic trimetallic MOF-derived Fe-Mn-Sn oxide heterostructure (FeMnO@Sn) with adjustable morphology, size and Sn content, prepared through an impregnation-calcination strategy.

In Situ Constructing Metal-Organic Complex Interface Layer Using Biomolecule Enabling Stabilize Zn Anode.

Aqueous zinc-ion batteries (ZIBs) are considered as a promising candidate for next-generation large-scale energy storage due to their high safety, low cost, and eco-friendliness. Unfortunately, commercialization of ZIBs is severely hindered owing to rampant dendrite growth and detrimental side reactions on the Zn anode. Herein, inspired by the metal-organic complex interphase strategy, the authors apply adenosine triphosphate (ATP) to in situ construct a multifunctional film on the metal Zn surface (marked as ATP@Zn) by a facile etching method.

Preparation and characterization of PMT-TiO-NTs@NiO-C/Sn-Sb composite electrodes by a two-step pulsed electrodeposition method for the degradation of crystalline violet.

To overcome the limitations imposed by Sn-Sb electrodes, the titanium foam (PMT)-TiO-NTs@NiO-C/Sn-Sb composite electrodes with cubic crystal structure are synthesized by introducing NiO@C nanosheet arrays interlayer on the TiO-NTs/PMT matrix through hydrothermal and carbonization process. Then a two-step pulsed electrodeposition method is used to prepare the Sn-Sb coating. Benefiting from the advantages of stacked 2D layer-sheet structure, the obtained electrodes exhibit enhanced stability and conductivity.

When MXene (TiCT) meet Ti/PbO: An improved electrocatalytic activity and stability.

Stable electrode materials with high catalytic activity are urgently required for electrochemical degradation of refractory organic pollutants in wastewater treatment. Herein, high conductive MXene (TiCT) was firstly fabricated by electrophoretic deposition (EPD) as an interlayer for preparing a novel PbO electrode. The well-conducted TiCT interlayer significantly improved the electrochemical performance of the EPD-2.
