Electrochemically grown porous platinum layers exhibit charge accumulation gradients. Here, the authors show that composite materials that rely on localized electrochemical growth of porous platinum can be applied as electrocatalysts for CO2 conversion, to tune the optical response of infrared metamaterials, and as broadband absorbers in optical sensors.
