A Noble-Metal-Free System for Photodriven Catalytic Proton Reduction



original image

Who needs the nobles? Ideally, devices to harvest solar energy into fuels would, in addition to having very high turnover numbers, make use of earth-abundant materials. In this Highlight we focus on a recent example in which a copper-based photosensitizer is used, in combination with an iron-based catalyst for light-driven proton reduction.
