Scientists developed artificial photosynthesis in order to find new hopeful solutions to harvest and reserve solar energy more efficiently, says a report published today by research team in the Proceedings of the National Academy of Sciences.
The novel dual-atom, iridium catalyst has been synthesized by a team of researchers from the United States and China. The catalyst has just two active metal centers and it is dedicated to act like a platform to the new artificial photosynthesis.
New study reveals that the catalyst, which is a well-defined structure, is most significantly able to serve a productive platform to the futuristic evolution in the theory of solar fuel synthesis. In addition, the researchers also attempted the X-ray analysis at the Advanced Light Source – Lawrence Berkeley National Laboratory that helped them determine iridium catalyst structure.
Two techniques were mainly involved in the measurements of X-ray experiments, one of which is X-ray Absorption Near Edge Structure (XANES) and another is X-ray absorption fine structure (EXAFS). During the experiments, they found critical evidence helping better exploring the catalyst.
Dunwei Wang, leading author of the study and Associate Professor of Chemistry at Boston College said in a statement that, “Our research concerns the technology for direct solar energy storage. It addresses the critical challenge that solar energy is intermittent. It does so by directly harvesting solar energy and storing the energy in chemical bonds, similar to how photosynthesis is performed but with higher efficiencies and lower cost.”
