| Abstract Scope |
Achieving net zero emissions by 2050 is a target set by most developed countries. CO2 recycling using solar energy is a strategy explored to achieve this goal. Solar photocatalytic and photoelectrochemical CO2 conversion processes enable recycling. These processes use semiconductors to absorb solar photons and generate energetic charge carriers to perform redox reactions leading to fuel production. While these are promising sustainable technologies, they are only in the initial stages of development. Low dimensional materials that are stable and efficient in harvesting and utilizing solar energy can bring significant improvements in these technologies. We have developed unique nanostructured semiconductors and studied their performance as photocatalysts. Numerical simulations have also been used to investigate the propagation of light waves through such materials and obtain important information about appropriate geometries required for maximum light absorption. In this presentation, the results of these experimental and simulation studies are discussed. |
