Biofuels are fuels produced from hydrocarbon-rich living organisms (biomass) — such as plants or microalgae — by thermal, chemical or biochemical conversion processes. As with fuels, biofuels such as biodiesel, biogas and syngas are combusted to generate energy.

    Photocatalytic H2 production using semiconductors is a promising approach to store solar energy as a chemical fuel, but the oxidizing power of the excited holes is often wasted. Now, holes are harnessed in a dehydrocoupling strategy that simultaneously produces H2 and diesel fuel precursors from biomass-derived molecules.

    A significant portion of the energy required to electrochemically reduce CO2 to fuels and chemicals is typically consumed by the accompanying oxygen evolution reaction. Now, researchers show that alternative oxidative reactions using biodiesel-waste could improve the economics and emission profiles of this process.
