Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

open access: yesCarbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

open access: yesCarbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

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

open access: yesCarbon 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 ...
