Amorphous Protective Layers to Reshape Inorganic‐Rich Interphases for High‐Voltage Sodium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...

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.

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

open access: yesCarbon 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
