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 ...

High Quality MoS2 Layered Thin Films Obtained by Ionized Jet Deposition Investigated by X‐ray Absorption Spectroscopy at S L2,3 and Mo M2,3 Edges

Advanced Materials Interfaces, EarlyView.
Soft x‐ray absorption spectroscopy at the S L2,3 and Mo M2,3 edges reveals synthesis‐dependent electronic and structural order in MoS2. Bulk, exfoliated, and CVD samples show well‐resolved 2D features, while as‐deposited IJD films appear amorphous but crystallize into ordered 2H‐MoS2 upon moderate annealing, confirming IJD as a viable low‐temperature ...

Spin-dependent electrocatalysis

National Science Review
ABSTRACT The shift towards sustainable energy requires efficient electrochemical conversion technologies, emphasizing the crucial need for robust electrocatalyst design. Recent findings reveal that the efficiency of some electrocatalytic reactions is spin-dependent, with spin configuration dictating performance.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
