Mimicking photosynthesis is not easy. The bottleneck of artificial photosynthesis is visible light as converting it into other energy is not efficient. Researchers at Michigan Technological University have found a way to solve this issue, leading to an efficient technique to produce hydrogen fuel. Last week, the Journal of Physical Chemistry published their work.

The technique was developed by Yun Hang Hu, the Charles and Carroll McArthur professor of Materials Science and Engineer, and his PhD student, Bing Han, at Michigan Tech.

"Hydrogen is the future of cars," says Hu. "And if you want to power hydrogen cars, you have to make hydrogen fuels."

In this new hydrogen production process, the key is to understand the interactions of a catalyst, light and a sacrificial molecule. The method could make the sustainable production of hydrogen fuels more efficient.
