Nickelferrite on Pnictogen Functionalized Carbon Nanohorns. Bifunctional ORR and OER Catalysts in Rechargeable Zinc‐Air Batteries

open access: yesAdvanced Science, EarlyView.
A systematic study on the performance of N,P‐doped NiFe2O4@CNH bi‐functional hybrid electrocatalysts for rechargeable zinc‐air batteries is presented. The importance of P, N‐doping and the intimate tethering of nickel‐ferrite nanocubes on the carbon nano‐horn (CNH) surface which are well dispersed on the surface of N,P doped CNHs.

Aryl‐Tethered Pendant Sterically Shielded Imidazoliums for Durable Anion Exchange Membranes

open access: yesAdvanced Science, EarlyView.
An aryl‐tethered, sterically shielded imidazolium architecture protects cationic sites from hydroxide attack while avoiding vulnerable benzylic cation–polymer linkages. Incorporated into poly(arylimidazolium) membranes, this dual‐protection design enhances alkaline and oxidative durability and supports prolonged alkaline water electrolysis, offering a ...

Interface‐Enhanced Electrochemical Epoxidation Over a Core‐Shell Nanozeolite TS‐1@Mn‐N‐C Catalyst

open access: yesAdvanced Science, EarlyView.
Core–shell interface of TS‐1@Mn‐N‐C enables in situ generation of high‐concentration H2O2 and its spatially confined activation toward epoxidation‐active η‐Ti‐OOH species, leading to highly efficient and continuous electrochemical epoxidation. The work successfully addresses the key challenge of inefficient mass transfer and slow kinetics caused by ...

Pt‐Regulated Dynamic Cu(0) Regeneration in CuPt Alloy Enables High‐Efficiency Self‐Driven Formaldehyde Fuel Cells for Potassium Formate Production

open access: yesAdvanced Science, EarlyView.
In this work, a Cu30PtX/CF anode material was synthesized to effectively catalyze the electrocatalytic formaldehyde oxidation, and thereby assembled a fuel cell that offered a high open‐circuit potential of 0.94 V and a power density of 34.3 mW cm−2. This work realizes the co‐generation of electrical energy and high‐value‐added chemicals with nearly ...

Excellent Thermoelectric Performance Realized in SnSe Materials via Chemical Bond Tailoring Using GeTe as Molecule Scissors

open access: yesAdvanced Science, EarlyView.
The GeTe acting as “molecule scissors” can tailor chemical bond, the breaking of Ag‐Se bonds and the formation of Ge‐Se bonds occur in the A‐SnSe matrix, along with the formation of Ag2Se precipitates. This process helps to optimize the thermoelectric properties, and also improves its mechanical properties to a certain extent.

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

open access: yesAdvanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

open access: yesAdvanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated
