CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

Advanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

All‐Inorganic InP/ZnSe/ZnS Quantum Dots with Chalcogenidometallate Ligands for Biosolar Catalysis

Advanced Functional Materials, EarlyView.
Intrinsic charge transfer limitations in core/shell QDs are addressed through a ligand‐induced band offset engineering (LBOE) strategy utilizing metal chalcogenide complex (MCC) ligands. The MCC‐functionalized InP/ZnSe/ZnS QDs exhibited remarkably augmented hydrogen peroxide (H2O2) generation.

Boosting the Energy Density of “Anode‐Free” Lithium Metal Batteries via Electrospun Polymeric Scaffolds

Advanced Functional Materials, EarlyView.
While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...
