Carbon Dot Nano‐Spacers in Triazine Networks for Integrated Photothermal Seawater Desalination and H2O2 Production

Carbon Energy, EarlyView.
Cyanated carbon dots (CN‐CDs) are synthesized by the hydrothermal method with carboxymethyl cellulose and cyanobenzoic acid, and CD‐CTN is obtained in situ via cyclotrimerization of CN‐CDs. CD‐CTN possesses excellent photothermal catalytic H2O2 production in seawater, and desalted H2O2 could be obtained, which demonstrates the practical application for

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

Carbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER

Carbon Energy, EarlyView.
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200

Entropy‐Stabilized Pd/HEO Bifunctional Catalyst for Selective Aqueous‐Phase Hydrogenolysis of Cellulose to Ethylene Glycol

EcoEnergy, EarlyView.
An entropy‐stabilized Pd/HEO catalyst integrates Lewis acid and hydrogenation sites within a robust oxide–metal interface, enabling efficient and selective conversion of cellulose to ethylene glycol (68.3%) in water. ABSTRACT The selective conversion of cellulose into ethylene glycol (EG) under aqueous conditions is an attractive yet challenging route ...
