Taking a cue from the mechanism that trees use to convert carbon dioxide into sugars, researchers have found a similar way to turn the gas produced by the burning of fossil fuels in power plants and car engines into a usable energy source using sunlight. As scientists and policymakers around the world try to combat the increasing rate of climate change, they have focused on the chief culprit — carbon dioxide.

Output of research
While plants use their catalysts to make sugar, the researchers used theirs to convert carbon dioxide to carbon monoxide. Although carbon monoxide is also a greenhouse gas, it is much more reactive than carbon dioxide and scientists already have ways of converting carbon monoxide into usable fuel, such as methanol.
