Influence of sub-zero temperature on nucleation and growth of copper nanoparticles in electrochemical reactions
Summary: Cu metal nanostructures have attracted wide interest of study as catalysts for CO2 reduction reaction and other applications. Controlling the structure and morphology of Cu nanostructures during synthesis is crucial for achieving desired properties. Here, we studied temperature effects on e...
