Quantifying Spatio‐Operational Heterogeneity in Electrochemical Devices via Operando Correlative Neutron and X‐Ray Tomography

open access: yesAdvanced Functional Materials, EarlyView.
Heterogeniety in electrochemical systems heavily influences device performance and durability. The study shows unique evidence of spatio‐operational heterogeneity in fuel cells via operando neutron and X‐ray tomography. Large variations in membrane thickness and hydration depend upon location and operating conditions, with implications on membrane ...

Ion and Solvent Dynamics in Charged 2D Clay Nanoslits with Unprecedented Ångström‐Precise Slit Height Control

open access: yesAdvanced Functional Materials, EarlyView.
The slit height of fluorohectorite 2D‐nanochannels is tuned with Å‐precision (2.4–250 Å). Slit‐height‐dependent ion and water mobilities are quantified by applying EIS, PFG‐NMR, and SFG‐NMR with MD simulations guiding interpretation. Diffuse properties are investigated with CP‐AFM, MD, and PB.

Bipolar Hydrogen Production by Hybrid Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
This review focuses on the recent advances in uniqueness bipolar H2 production from the oxidation of representative small molecules, including 5‐hydroxymethylfurfural, formaldehyde, alcohols, and N‐heterocycle amides. The target electrocatalysts and the underlying mechanisms are discussed in respect to specific substrate oxidation.

PbCrO4/Pb Hybrid with Surface Unsaturated Metal Sites for Efficient CO2‐to‐Formate Reduction

open access: yesAdvanced Functional Materials, EarlyView.
An in‐operando electrochemically synthesized Vo‐rich PbCrO4/Pb hybrid exposes abundant unsaturated metal sites on PbCrO4 surface, which facilitates CO2 activation and stability of *OCHO intermediates. Simultaneously, the bulk Pb nanorod significantly enhances the conductivity of electrode for fast charge transport. The Vo‐rich PbCrO4/Pb electrocatalyst
