Research: Polymer-based System Breaks Records for Capture of CO2

A group of U.S. scientists say they have successfully used solid materials based on fumed silica impregnated with polyethylenimine (PEI), a readily available and inexpensive polymeric material, to increase the levels of carbon dioxide (CO2) captured direct from air or concentrated sources of CO2 such as the flue gas from power plants. The research was published recently in an edition of the Journal of the American Chemical Society. The scientists state in the research paper that the CO2 removal rate achieved using polyethylenimine is among the highest ever...
