Unlocking Three‐Dimensional Electron and Ion Transport in High‐Loading and Dense Lithium‐Ion Battery Electrodes Assisted via Porous Graphene Networks

Advanced Energy Materials, EarlyView.
Graphene mesosponge (GMS) enables three‐dimensional electron and ion transport in high‐loading, densely packed lithium‐ion‐battery electrodes through its unique mesoporous structure. The three‐dimensionally interconnected carbon network and electrolyte retained within the GMS mesopores ensure efficient electronic and ionic conduction, respectively ...

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

Angewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Mechanochemically Disordered Li2Ta2OCl10 Oxyhalide Unlocks Superionic Conductivity (>10 mS.cm−1)

Advanced Energy Materials, EarlyView.
This work presents a new crystalline oxyhalide, Li2Ta2OCl10, built from [Ta2OCl10]2− dimers. The disorder induced by ball‐milling drives the dramatic 5000‐fold increase in ionic conductivity to reach 11 mS.cm−1. The material shows promise as a solid electrolyte for batteries and opens new prospects for the discovery of new dimer‐based compounds ...

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp3 Hybridization

Angewandte Chemie, EarlyView.
A new carbon allotrope with mixed sp–sp3 hybridization has been synthesized through delicately controlled kinetics at a liquid–liquid interface. The resulting material, termed diamondiyne, exhibits an expanded diamond‐type network in the form of small crystallites in a continuous all‐carbon film.

Ionomer‐Free Iridium Anodes With Low Loading for Zero‐Gap Electrolyzers via Direct Atomic Layer Deposition

Advanced Energy Materials, EarlyView.
Iridium‐based anode catalyst layers for proton exchange membrane water electrolysis were fabricated via atomic layer deposition (ALD). Using custom‐made microporous substrates and thermal ALD, current densities of up to 2.5 A·cm−2${\rm A}\cdot{\rm cm}^{-2}$ at 0.21 mg·cm−2$\text{mg}\cdot {\text{cm}}^{-2}$ Ir loading were achieved.

Lattice Nitrogen Couples Cuδ+ Stabilization With Pathway Control for CO2‐to‐Methanol Electroreduction

Angewandte Chemie, EarlyView.
Lattice‐incorporated nitrogen regulates amorphous CuO by forming a resilient Cu─N/O coordination environment that suppresses excessive Cu reduction and preserves Cuδ+ sites under reducing conditions. The resulting catalyst enables selective CO2‐to‐methanol conversion, achieving a methanol Faradaic efficiency of 48% in an H‐type cell and a methanol ...

Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

Angewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

Chalcogen‐Bond‐Driven Electrochemical Bromide Sequestration in Benzothiazole‐Functionalized Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
To address the unresolved challenge of selective bromide removal from reverse‐osmosis permeate, we developed benzothiazole‐functionalized COF/rGO electrodes that exploit directional chalcogen bonding to preferentially capture Br− over Cl−. The mesoporous BTzTp@rGO electrode achieved a maximum Br− uptake of 36.7 mg g−1, a Br−/Cl− selectivity factor of ...
