Scientists at University of Illinois have developed an Artificial Leaf that can take up CO2 from atmosphere 10 times more than natural leaves.
What is an Artificial Leaf?
Artificial leaf mimics the process of photosynthesis where it absorbs the CO2 present in the atmosphere and converts it into carbohydrates.
How does this Artificial Leaf works in the new model?The Artificial leaf is enclosed in a capsule that is filled with water. When sunlight falls on the leaf, the water starts to evaporate leaving the bubbles around (bubbles create vacuum). The CO2 present in the atmosphere rushes to fill that void and thus the CO2 is absorbed by the Artificial Leaf and it gets converted into carbohydrates.
