    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 wealth of candidates are being investigated to improve the catalysts found in acidic and alkaline electrolysers. However, attention should be focused on developing stable water oxidation catalysts with improved intrinsic activity — not only increased geometric activity — alongside best practice for data collection.

    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.

    While recent gains in the efficiency of photoelectrochemical devices for hydrogen production are encouraging, high efficiency is rarely combined with high power output, which is important for large-scale viability. Towards this goal, researchers now demonstrate a promising thermally integrated device driven by concentrated solar irradiation.
