Uppsala team develops composite polymer dots for efficient, stable H2 production from water and sunlight

Green Car Congress

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. These polymer dots are designed to be both environmentally friendly and cost-effective.

MIT engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets. Auto-catalytic self-templating of 2DPA-1.

Israeli team develops decoupled PEC water-splitting system for centralized production of H2

Green Car Congress

Researchers in Israel have designed a separate-cell photoelectrochemical (PEC) water-splitting system with decoupled hydrogen and oxygen cells for centralized hydrogen production. It addresses the challenges of designing, building, and optimizing the device for assessing large-scale hydrogen generation. Landman et al.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. It utilizes water and sunlight to get chemical fuels.

Researchers develop organic semiconductor photocatalyst with enhanced hydrogen evolution

Green Car Congress

Currently, most hydrogen evolution photocatalysts (HEPs) are made from single-component inorganic semiconductors. These can only absorb light at ultraviolet wavelengths—constituting less than 5% of the solar spectrum—which limits their efficiency. A paper on their work appears in Nature Materials.
