Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−

Advances in Design Strategy and Mechanism Insights for Alkaline Hydrogen Evolution Reaction: Multilevel Site Engineering and Structure–Activity Relationship

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review is about material design based on engineering multilevel sites from theoretical calculation and synthetic routes to mechanism, structure–activity relationship, challenges and perspectives for boosting hydrogen production in alkaline electrolyte. Electrolytic water splitting is a clean, carbon‐free method for producing green hydrogen and has

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

Polarization‐Reoriented Piezocatalysis Enables Plastic Upcycling with Mechanical Energy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mixed plastic waste remains difficult to upcycle selectively under mild conditions, and piezocatalysis has been constrained by a persistent see‐saw effect: Stronger piezoelectric polarization tends to divert charge carriers away from the very active sites that drive catalysis. Sha et al.
