Abstract
Provided herein are TiO2-x nanoparticles and materials that show unusual photophysical and optical properties. These TiO2-x particles and materials can be used as efficient photocatalysts for the reduction of CO2 with H2O to produce CH4. Also provided herein are methods of making TiO2-x nanoparticles using a polymer-derived mesoporous carbon (PDMC) as a template.
Claims9
A material comprising TiO2-x nanoparticles, wherein:
- the material has a light absorption onset of about 400 nm to about 510 nm;
- x is a number ranging from 0.001 to 0.100;
- the nanoparticles have a substantially uniform size;
- the nanoparticles have an average size of about 5 to about 12 nm;
- and
- the material has an average pore size of about 5 to about 12 nm.
