Step‐Edge Functionalization by N‐Heterocyclic Carbenes Enhances Catalytic Activity in Electrochemical CO2 Reduction

Advanced Materials, EarlyView.
Atomically precise functionalization by N‐heterocyclic carbenes enhances the catalytic efficiency of macroscopically defined step edges toward electrochemical CO2${\rm CO}_2$ reduction. Sub‐molecular imaging reveals conformational differences between specific NHCs, which can be correlated with their catalytic performance. Photoelectron spectroscopy and

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

An integral metric for evaluating electrocatalytic activity

Chemija
This study introduces an integral metric of electrocatalytic activity, which is based on the comparison of the area under the polarisation curve in current density vs overpotential coordinates over a specific chosen overpotential range. This metric is applied to evaluate and compare several electrocatalysts, allowing for a more comprehensive ...

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

Advanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Magnetic‐Field Modulation of Charge Transport in Non‐Fullerene Semiconductors for Enhanced Hydrogen Evolution

Advanced Materials Interfaces, EarlyView.
ABSTRACT This study demonstrates that weak magnetic fields (16–40 mT) increase the efficiency of the hydrogen evolution reaction (HER) in electrocatalysts based on non‐fullerene acceptor (NFA) derivatives IT‐4Cl and Y6. Electrochemical measurements reveal that the application of the magnetic field reduces the onset potential and increases the current ...
