Thermally Assisted Photocatalytic Dehydrogenation of Methanol in Continuous Steady‐State Operation

Advanced Science, EarlyView.
Thermally assisted photocatalytic methanol dehydrogenation on Pt/TiO2 enables formaldehyde and hydrogen production far beyond thermodynamic limits. Continuous operation delivers up to 95% selectivity over 70 h, and oxygen microdosing strongly boosts conversion by regenerating surface oxygen sites.

Trace Li Pre‐Doping of Activated Carbon Cathode Enabling Accelerated Li‐Ion Transport for High‐Power Lithium‐Ion Capacitors

Advanced Science, EarlyView.
Trace‐level Li pre‐doping on activated carbon cathodes is demonstrated to significantly enhance Li‐ion transport and high‐rate performance in lithium‐ion capacitors. An ultrathin Li2CO3 interfacial layer, formed through controlled thermal conversion, facilitates rapid ion transport without pore blockage.

Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

Advanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...
