Coral‐Biomimetic Structured Organic Electro‐Oxidations With Exceptional High‐Current Catalytic Performance

Advanced Science, EarlyView.
A strategy for energy‐efficient hydrogen production coupled with biomass valorization via organic electrooxidation reactions is reported. A bio‐inspired multiscale coral‐like heterostructure catalyst delivers record‐breaking OEOR performance enabled by a dual‐copper synergistic Cu+/Cu2+–Ni mechanism, establishing a universal architectural and ...

stichwort OER

merz | medien + erziehung, 2016
Bildung für alle – frei, gleich, kostenlos. So oder so ähnlich ließe sich die Vision vielleicht zusammenfassen, die hinter dem Phänomen OER, Open Educational Ressources, steht. Wissen, Informationen, (Lern-)Materialien sollen – wenn es nach OER-Befürworterinnen und -Befürwortern geht– jederzeit und für jedermann frei zugänglich sein, sowohl in der ...

Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Intelligent Polymer Electrolytes for Next‐Generation Zinc‐Based Energy Storage Devices

Advanced Science, EarlyView.
Intelligent polymer electrolytes are organized into a three‐level hierarchy that advances zinc‐based energy storage from passive ion conduction toward active, adaptive, and intelligent operation. Molecular regulation of Zn+ coordination, water activity, desolvation, ion flux, and interfaces underpins adaptive self‐healing, anti‐freezing, adhesion, and ...

Glycerol‐Regulated Cytocompatible, Self‐Healing Gel Electrolyte Stabilizes Zinc Metal Anodes for Quasi‐Solid‐State Aqueous Batteries

Advanced Science, EarlyView.
A glycerol‐regulated PVA/PEG self‐healing gel electrolyte reconstructs the hydrogen‐bonding and Zn2+ coordination environments, suppressing water‐related parasitic reactions and enabling regulated Zn nucleation and homogeneous deposition. The resulting quasi‐solid‐state electrolyte combines durable Zn‐metal reversibility, self‐healing functionality ...
