Covalent Organic Framework and Carbon Nitride Composite for Scalable Solar Reforming

Advanced Materials, EarlyView.
A modular composite, containing a covalent organic framework, indium tin oxide, carbon nitride and nickel based molecular catalyst, enables solar reforming under neutral aqueous conditions, converting polyols and sugars into formate while generating H2.

Heterogenized Copper(II) Phenanthroline Catalysts for Electroreduction of CO2 to C2 Compounds: Substitution on the Ligand Causes Structural Changes to the Molecular Framework and Stability Enhancement

Advanced Materials, EarlyView.
Based on a previously reported binuclear Cu(II) phenanthroline catalyst, a structurally modified version with enhanced stability for electrochemical reduction of CO2 is developed. The second‐generation system allows for stable operation in an MEA electrolyzer with a Faradaic efficiency of >70% for C2 products at elevated current densities.

Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Single‐Crystal Organic Field‐Effect Transistors Based on 5,15‐Bisaryl‐Tetrabenzoporphyrins: Synthesis, Structure, and Charge Transport Properties

Advanced Materials Interfaces, EarlyView.
This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...
