Abstract
Compositions comprising highly reflective microcrystalline/amorphous materials are provided. In some instances, the highly reflective materials are microcrystalline or amorphous carbonate materials, which may include calcium and/or magnesium carbonate. In some instances, the materials are CO2 sequestering materials. Also provided are methods of making and using the compositions, e.g., to increase the albedo of a surface, to mitigate urban heat island effects, etc.
Claims18
A method of enhancing the albedo of a surface of a roof shingle surface, the method comprising:
- applying to the roof shingle surface a carbonate material so that the carbonate material is present only on the surface of the roof shingle, wherein the carbonate material comprises a CO2 sequestering carbonate compound that is produced by a method comprising:
- (a) contacting a CO2 containing gas with a bicarbonate buffered aqueous medium having a pH that ranges from 8 to 10 under conditions sufficient to produce a bicarbonate rich product that comprises droplets of a liquid condensed phase (LCP) in a bulk liquid;
- and
- (b) combining the bicarbonate rich product with a cation source under conditions sufficient to produce a solid carbonate composition comprising the CO2 sequestering carbonate compound.
