Title:
SEQUESTRATION AND RELEASE OF CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2013/072906
Kind Code:
A3
Abstract:
A method for reversible capture and release of carbon dioxide comprises the steps of providing a solution of a defined tetranuclear complex or mixture thereof, in which absorption sites are provided by coordinated solvent molecules such as water molecules. The solution is exposed to the atmosphere or to a gas stream containing carbon dioxide to sequester carbon dioxide, and the pH of the resultant reaction mixture is adjusted to facilitate the release of carbon dioxide. The solution which is used to sequester carbon dioxide is a solution of a polynuclear transition metal compound having the formula: (I) and the tetranuclear transition metal compound that has sequestered carbon dioxide is of the formula: (II)
