Scientists at Sweden’s Uppsala University have developed a new type of polymer dot photocatalyst that enhances the production of green hydrogen.

Photocatalysts can separate the hydrogen and oxygen components in water using sunlight, resulting in green hydrogen which can then be integrated into the energy system as a renewable power source.
Until now, these photocatalysts have generally been derived from metals, which can be expensive and in many cases toxic, jeopardising the technology’s green credentials.
Researchers at Uppsala University have developed photocatalytic composite polymer nanoparticles (“polymer dots”) that show promising performance and stability for the production of hydrogen from water and sunlight. An open-access paper on the work appears in the Journal of the American Chemical Society. These polymer dots are designed to be both.

Abstract:
Hydrogen for energy use can be extracted in an environmentally friendly way from water and sunlight, using photocatalytic composite polymer nanoparticles developed by researchers at Uppsala University. In laboratory tests, these polymer dots showed promising performance and stability alike. The study has been published in the Journal of the American Chemical Society.
