Nano-sandwich photocathode improves solar conversion of CO₂ into ethanol

Czech researchers at Charles University in Prague, led by Pavla Eliášová, have developed an advanced photocathode that helps convert the greenhouse gas carbon dioxide into pure ethanol using sunlight. The new technology solves a long-standing problem of material degradation in water, achieves record conversion efficiency and opens the way toward sustainable production of green fuels. The paper is published in the journal Advanced Energy Materials.
