2017: Breakthrough Artificial Photosynthesis Cleans Polluted Air, Makes Energy

An invention by scientists at the University of Central Florida turns greenhouse gases into clean air, producing fuel at the same time. By mixing titanium with organic molecules, they created metal-organic frameworks (MOFs) tuned to blue light. These ‘light-harvesting antennae’ created reactions which turned CO2 into two reduced forms of carbon, formate, and formamides, described as two kinds of solar fuel. … the system could one day be set up next to facilities that emit large amounts of carbon dioxide, where it would capture the CO2 and break it down into harmless organic materials, creating solar fuel in the process. … ‘This work is a breakthrough,’ said UCF Assistant Professor Fernando Uribe-Romo. ‘Tailoring materials that will absorb a specific color of light is very difficult from the scientific point of view… While scientists have long investigated the idea, it’s remained difficult to find a way for visible light to […] Read More
