B, N‐Co Doped Porous Carbon Nanotubes Supported Cu Single Atoms and B‐Doped Cu Nanoparticles for High‐Performance Electrocatalytic NO3RR and Zn‐Nitrate Batteries

Carbon Energy, EarlyView.
The ToC image shows a porous B, N‐doped carbon nanotube decorated with B‐doped Cu nanoparticles for nitrate‐to‐ammonia conversion. The unique structure enhances charge transport, promotes the adsorption and activation of key intermediates, alters the rate‐determining step, suppresses hydrogen evolution, and improves NH3 yield and Faradaic efficiency ...

Regulating Interfacial Water Structure on CoNi/MoN Heterostructures Boosts Electrocatalytic Nitrate Reduction to Ammonia

Carbon Energy, EarlyView.
The CoNi/MoN interface effect induces electron transfer from CoNi species to MoN nanosheets, in which electron‐enriched CoNi/MoN interface captures K+ to form K+‐H2O, facilitating H2O dissociation to provide *H for accelerating hydrogenation steps, while electron‐deficient CoNi nanoparticles enhances the NO3− adsorption and reduces the free energy ...

Strongly‐Anchored Ionomer‐Free Anode Catalyst Layer Fabricated via Joule Heating Achieves Efficient Electron/Mass Transfer for Acidic Water Electrolysis

Carbon Energy, EarlyView.
An ionomer‐free anode catalyst layer is fabricated via rapid Joule heating, partially embedding IrO2 nanoparticles into the membrane to form a robust, anchored interface. This architecture eliminates ionomer‐induced poisoning and mass‐transport barriers, enabling efficient water‐mediated proton transport and electronic connectivity.

Formic‐Acid In Situ Hydrogen Enables Programmable Ru–Pd–Pt/C Trimetallic Interfaces for Durable Acidic HER

Carbon Energy, EarlyView.
Bamboo diaphragm−derived carbon is used as a support to prepare Ru–Pd–Pt/C catalysts through a stepwise reduction strategy. The Ru–Pd interface promotes formic acid activation and induces Pt deposition. The metallic interface of Ru–Pd–Pt/C enables H* generation, transfer, and recombination, thereby improving Pt utilization, acidic HER activity, and PEM
