. Heterogeneous catalysts are widely used in energy and environmental applications. However, conventional catalysts do not currently possess the required efficiency for producing solar-converted clean fuels or for pollution abatement. On the basis of our expertise in nanomaterials and photocatalysis/catalysis, we propose to develop two new classes of nanocatalysts: (1) efficient sunlight driven hybrid nanostructured photocatalysts for clean energy. Here, the target is to design new solar fuel generation systems with the required efficiency, scalability, and sustainability to be economically viable. The photocatalytic conversion of H20 and CO2/H20 under sunlight to valuable energy vectors and fuels is one of potential solutions to both the global warming and energy shortage problems. The principal challenge of sunlight-to-fuel generation lies in designing an efficient photocatalytic system; (2) nanocrystalline porous hybrid catalysts for environmental remediation. Here, the target is to design new efficient catalyst systems for NOx and CO pollution abatement from mobile and stationary sources for commercial applications. The control of NOx and CO emission from automobiles remains challenging for both industry and academic researchers.
