High CO2 Adsorption Material Based on Polyethyleneimine
Recently, a research team led by Professor George Olah, the 1994 Nobel Laureate in Chemistry from the University of Southern California, successfully developed a high CO2 adsorption material based on polyethyleneimine. The researchers first dissolved polyethyleneimine into methanol solvent and then poured this solution into silica (glass) materials in a molten gasification state while stirring. After the methanol evaporates and the silica cools down, a porous solid material is formed. Tests have shown that this material has a CO2 adsorption rate of 1.72 nanomoles per gram at room temperature, which is the highest to date. When heated to 85℃, all the CO2 is completely released, and the material can be reused. Experts believe that this material could help address climate change. The pure CO2 collected through this method can be combined with hydrogen extracted from seawater to generate fuel methanol.
