Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

open access: yesEcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...

High resolution investigation of localized corrosion by in-situ Scanning Kelvin Probe Force Microscopy

open access: yes, 2011
In dieser Arbeit wurde die Möglichkeit zur Nutzung der Scanning Kelvin Probe Force Microscopy (SKPFM) in der Korrosionforschung untersucht. Ein wesentlicher Nachteil dieser Technik ist die mangelnde Fähigkeit der Abbildbarkeit durch organische Beschichtungen hindurch.

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

open access: yesEcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...
