From model to realistic copper sulfide electrocatalyst — •Roser Fernandez Climent, Jesus Redondo, and Martin Setvín — Charles University, Prague, Czech Republic

Copper sulfide is a widely studied material in electrocatalysis. In this study, we synthesized copper sulfide thin films electrochemically under inert conditions, enabling precise control of material properties and minimizing contamination risks. The films were transferred in-vacuum for surface characterization using X-ray photoelectron spectroscopy (XPS), low-energy electron diffraction (LEED), and scanning transmission electron microscopy (STEM).
