Although scientists have flirted with artificial photosynthesis before, we are now one step closer to having the technology available in a practical manner thanks to researchers at Florida State University, as outlined in a press release. The team created a single-layer manganese oxide material that can effectively capture sunlight and lead to its breakdown into hydrogen and oxygen, as outlined in the study.
"In theory, this should be a self-sustaining energy source," said Jose L. Mendoza-Cortes, who led the study. "Perhaps in the future, you could put this material on your roof and it could turn rain water into energy with the help of the sun."
The device is unique in its ability to create energy without the downside of any waste products. "You won't generate carbon dioxide or waste," he said.
In addition to the benefits of reduced waste, only a small amount of the single-layer manganese oxide material is needed in order to capture sunlight. This is contrary to silicon, another common material that could be effective were it not for the fact that hundreds of pieces of material would need to be stacked in order to be effective.
"This is why the discovery of this direct band gap material is so exciting," said Mendoza-Cortes. "It is cheap, it is efficient and you do not need a large amount to capture enough sunlight to carry out fuel generation."
The technology still has a ways to go before it is ready to be integrated into home-based products, but it shows plenty of potential for real-world application - it could be used to help hydrogen-fueled cars generate their own energy supply as well as support homes with special roofs.
