Boosting Charge Storage in Ferri/Ferrocyanide‐Based Alkaline Redox Flow Batteries

Angewandte Chemie, EarlyView.
By modifying the solvation environment, cation engineering through Li+ substitution of traditional K+ or Na+ boosts the alkaline solubility of the ferri/ferrocyanide catholyte redox couple, providing a viable pathway to overcome the long‐standing challenge of energy density limitations for aqueous redox flow batteries (RBFs).

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

Angewandte Chemie, EarlyView.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

Separation und Valorisierung von Chlor aus Restgasströmen

Angewandte Chemie, EarlyView.
Es wurde festgestellt, dass ein handelsübliches Ionenaustauscherharz in Gegenwart anderer Gase selektiv Chlorgas adsorbiert und dabei reversibel die entsprechenden Trichlorid‐Spezies [IEx][Cl3] bildet. Diese Entdeckung wurde zu einem effizienten Verfahren für die Rückgewinnung und Verwertung von Chlor aus industriell reichlich vorhandenen ...

Maximizing Active Site Density in Tin Single‐Site Catalysts for Selective Carbon Dioxide to Formate Electroreduction

Angewandte Chemie, EarlyView.
High‐loading tin single‐site catalysts (>7.5 wt.% Sn) are synthesized using a nitrogen‐enriched carbon scaffold and mechanochemically assisted pyrolysis to stabilize atomically dispersed Sn. The resulting Sn/N‐C‐M catalyst enables highly selective CO2‐to‐formate conversion (>90% FE across 50–500 mA cm−2) with long‐term durability and operando‐verified ...
