Abstract:
A carbon dioxide absorbent comprising (i) a liquid, nonaqueous silicon-based material, functionalized with one or more groups that either reversibly react with CO 2 or have a high-affinity for CO 2 and (ii) a hydroxy-containing solvent is provided. The absorbent may be utilized in methods to reduce carbon dioxide in an exhaust gas, and finds particular utility in power plants.
Abstract:
A method of forming high-purity elemental silicon is disclosed. The method includes the step of heating a silica gel composition, or an intermediate composition derived from a silica gel composition, wherein the silica gel composition or intermediate composition includes at least about 5% by weight carbon, and the heating temperature is above about 1550°C. The heating step results in the production of a product which includes elemental silicon. Another aspect of the invention relates to a method for making a photovoltaic cell. The method includes the step of forming a semiconductor substrate from elemental silicon prepared as described in this disclosure. Additional steps are then undertaken to fabricate the photovoltaic device.
