摘要:
The disclosure provides a metal oxide-doped titanium dioxide (TiO 2 ) composition, with a solid phase including TiO2 and one or more metal oxides and a liquid phase. Methods of preparing such doped compositions are also provided. The doped compositions disclosed herein can exhibit adsorption and photocatalytic properties, particularly in the context of treating gas streams containing H 2 S gas (e.g., to reduce atmospheric pollution).

Methods, systems, and devices are disclosed for fabricating and implementing optically absorbing coatings. In one aspect, an optically selective coating includes a substrate formed of a solar energy absorbing material, and a nanostructure material formed over the substrate as a coating capable of absorbing solar energy in a selected spectrum and reflecting the solar energy in another selected spectrum. A concentrating solar power (CSP) system includes heat transfer fluids (HTFs); thermal energy storage system (TES); and solar receivers in communication with HTFs and including a light absorbing coating layer based on cobalt oxide nanoparticles.
