Copper-doped TiO2 nanosheets turn CO2 into methanol under visible light
“Copper-doped TiO2 nanosheets convert CO2 into methanol under visible light. Draw molecules as simple labelled formulas (CO2, H2O, CH3OH, O2), not ball-and-stick models. Left: CO2 and water. Middle: a TiO2 nanosheet with copper sites; visible light excites electrons that reduce CO2 at the copper sites while holes oxidize water to O2. Right: methanol yield three times higher than undoped TiO2.”
