Researchers from the Brookhaven National Laboratory have increased the effectiveness of a chemical combination. The combination splits water molecules and captures light. Therefore, the purpose of such an invention is to enable building blocks to generate hydrogen fuels.
Additionally, this study offers a platform for the development of groundbreaking improvements in the process of artificial photosynthesis. This artificial photosynthesis is a lab-based copy of the natural photosynthesis, which comes with the aim of producing clean energy from the sunrays.
Mixture of Hydrogen Atoms with Pure Hydrogen Gas Shows the Way
In the process of natural photosynthesis, the green plants make use of sunlight for the transformation of carbon dioxide and water. The chemical bonds stock energy derived from sunlight that hold together those molecules.
Most of the artificial synthesis process tries to find out ways that would utilize light for splitting water into its original components, namely oxygen and hydrogen. This mixing of hydrogen with various other elements, preferably carbon from carbon dioxide, is to produce clean fuels. The mixing of hydrogen atoms with pure hydrogen gas is a way forward for production of solar powered clean fuel.
Researchers have been looking at an extensive range of light absorbing molecules that could be paired with various chemical catalysts. These molecules also need to pull apart the strong bond of hydrogen and oxygen of water.
The new method makes use of molecular “tethers”, which are carbon chains with strong affinity for one another. These tethers connect chromophore with the catalyst, which is a significant step for the activation of the catalyst. These tethers are responsible holding the particles close together so as to facilitate transfer of electrons from catalyst to the chromophore. It also ensures that electrons do not go back to the catalyst in the process.
