MoO2‐Mediated Ni─Fe Bond Contraction and Electronic Modulation in Ni3Fe Alloy for Efficient Water Electrolysis at High‐Current‐Densities

open access: yesAdvanced Materials, EarlyView.
MoO2 effectively modulates the electronic structure of Ni3Fe and optimizes the Ni─Fe bonding configuration, thereby enabling dual regulation of the Volmer‐Heyrovsky steps and the evolution pathways of reaction intermediates during the water electrolysis process, which collectively accelerates both the hydrogen evolution reaction and oxygen evolution ...

Sustainable Liquid Metal Composites for Soft Electronics and E‐Waste Reduction

open access: yesAdvanced Materials, EarlyView.
Liquid metal (LM) composites embody recyclability, repairability, renewability, and resilience (4R), offering a sustainable route for soft electronics. With exceptional conductivity, stretchability, and eco‐friendly recovery, these systems enable closed‐loop lifecycles and reduce e‐waste.

Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

open access: yesAdvanced Materials, EarlyView.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.

Heterogenized Copper(II) Phenanthroline Catalysts for Electroreduction of CO2 to C2 Compounds: Substitution on the Ligand Causes Structural Changes to the Molecular Framework and Stability Enhancement

open access: yesAdvanced Materials, EarlyView.
Based on a previously reported binuclear Cu(II) phenanthroline catalyst, a structurally modified version with enhanced stability for electrochemical reduction of CO2 is developed. The second‐generation system allows for stable operation in an MEA electrolyzer with a Faradaic efficiency of >70% for C2 products at elevated current densities.

Quantum Size Effect Synergizes Space‐Limited Domain Action for Advanced Aqueous Zinc‐Iodine Batteries

open access: yesAdvanced Materials, EarlyView.
A functionalized MOF, Al‐TCPP(Fe), featuring micropores and Fe‐N4 sites, acts as a superior iodine host for aqueous zinc‐iodine batteries. This dual‐function design synergistically confines polyiodides and catalyzes iodine redox through quantum‐size‐tuned Fe‐N4 sites.
