By “carbonizing” wheat flour, researchers at Purdue University have developed a porous substance that can capture carbon dioxide from flue gas, the Indiana institution announced Wednesday. Working with researchers at Korea University in Seoul, the scientists used potassium hydroxide to generate numerous small pores in wheat floor at a high temperature. Carbon dioxide can then be bound inside the pores, the release explains.
“The outstanding overall carbon dioxide adsorption performance indicates that potassium hydroxide-activated microporous carbon compartments can be a promising approach,” Korea University associate chemical engineering professor Ki Bong Lee said in the release.
