Photocatalysis

Photocatalysis is a type of catalysis that results in the modification of the rate of a photoreaction - a chemical reaction that involves the absorption of light by one or more reacting species - by adding substances (catalysts) that participate in the chemical reaction without being consumed.

    Photocatalytic systems for CO2 conversion to fuels tend to suffer from low selectivity, and sacrificial reagents or external bias are often required to make the reaction work. Now, a wireless and stand-alone photocatalyst device is demonstrated that converts CO2 and water into formate and O2 using solar energy without external bias.

    Reporting data according to standards accepted by the community is fundamental to the progress of science. In the broad area of catalysis, best practice principles are well consolidated in some subfields, but they are still developing in others.

    Photocatalytic conversion of methane to ethane suffers from low yields due to poor selectivity and quantum efficiency. Now, ethane is produced by a photochemical looping strategy using a nanocomposite of titanium dioxide, phosphotungstic acid and silver cations, with selectivity of 90% and quantum efficiency of 3.5% at 362 nm.

    Organic polymers have demonstrated promise as photocatalysts, but their photocatalytic efficiencies remain relatively low. Now, borrowing principles from organic photovoltaics, heterojunctions of polymer photocatalysts and small molecule acceptors have been shown to have excellent solar hydrogen production efficiencies.
