New material may help convert CO2 into fuel using light

New material may help convert CO2 into fuel using light

When exposed to visible light, the material, a “spongy” nickel organic crystalline structure, converted carbon dioxide (CO2) into carbon monoxide (CO) gas, which can be further turned into liquid fuels, solvents, and other useful products.

Small ponds emit large amount of greenhouse gases

Ponds play an important role in the carbon cycle as gases produced at the bottom of small ponds are able to reach the top more often than what occurs in larger lakes, due to greater water mixing and shallower waters.
