Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

Electrical Impedance Tomography Monitoring of Salt Transportation in Cellulose Hydrogel for Solar‐Driven Evaporative Desalination via Laser Defined Wettability

open access: yesAdvanced Functional Materials, EarlyView.
Solar‐driven evaporation is a promising solution to the global water crisis; however, it faces a significant challenge of salt accumulation during the evaporation process. This study introduces an innovative in situ electrical impedance tomography technique for real‐time monitoring of salt transportation in the evaporator.
