Artificial Photosynthesis May Alleviate Climate Change

Climate change is largely blamed on increased concentration of planet-warming carbon dioxide in the atmosphere from human activities such as the burning of fossil fuels for heat، electricity، and transportation، as the Technical Times said.

Artificial Photosynthesis May Help Repurpose Carbon Dioxide
However، artificial photosynthesis inspired by how plants convert sunlight، water، and carbon dioxide into carbohydrates and oxygen may help alleviate global warming.

Researchers from the University of Illinois managed to produce fuel through artificial photosynthesis. Just like in natural photosynthesis، the process involved the use of water، carbon dioxide and visible light.

By converting carbon dioxide into more complex molecules like propane، researchers are now a step closer to using excess carbon dioxide to store solar energy in the form of chemicals. Hydrocarbons created from the processes may be used to power fuel cells for generating electrical current and voltage.

The process can also provide a means to repurpose atmospheric carbon dioxide that wreaks havoc to the planet.

Converting Water And Carbon Dioxide Into Fuel
In the new study published in the journal Nature Communications، Prashant Jain and colleagues developed an artificial process that uses the same green light portion of the visible light spectrum used during natural photosynthesis to convert water and carbon dioxide into fuel.

"Sunlight-driven conversion of CO2 to fuels is particularly attractive as a means to store intermittent solar energy in the form of C-C and C-H bonds،" the researchers wrote in their study.
