Tailoring Iron Nanostructures on MoS2: The Pivotal Role of Sulfur Vacancies in Growth Morphology and Charge Transfer

Advanced Materials Interfaces, EarlyView.
The deposition of Iron on pristine MoS2/Au(111) monolayers produces nanoparticles that donate charge to the support, generating Fe+2‐interfacial species. On the contrary, on defect‐engineered MoS2, sulfur vacancies trap sub‐nanometric Fe clusters and host two excess electrons that redistribute locally, suppressing Fe oxidation without formal Mo ...

In Situ Formation of Ni‐P‐O‐C Interfaces in DLP‐Printed Carbon Microlattices for Efficient Alkaline Hydrogen Evolution

Advanced Materials Technologies, EarlyView.
Graphical abstract illustrating the fabrication of Ni–P–O–C porous carbon microlattice electrodes by DLP printing of Ni/P precursor‐containing resin followed by high‐temperature carbonization. The resulting conductive microlattice acts directly as the HER cathode in alkaline electrolyte, where in situ formed Ni–P–O–C interfaces provide active sites for

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 ...
