From The Engineer:
US researchers have developed a new material for capturing carbon dioxide (CO2) from the chimneys of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide and can be reused many times.
Existing CO2 capture techniques involve the use of solid materials that lack sufficient stability for repeated use, or liquid adsorbents that are expensive and require significant amounts of energy.
