Structural control of nanoparticles catalysts and sensors

Nanoparticles have been used in heterogeneous catalysis in the petrochemical industry for selective hydrogenation and oxidation reactions for many years, and it has long been realized that metallic nanoparticles can used to improve the sensitivity and selectivity of solid-state gas sensors. My long-term research objective is to develop highly selective and ultra-sensitive nanoparticle catalysts and sensors through the control of the size, shape, structure, and composition of nanoparticles, and precisely controlling the nanostructural and microstructural ordering of the nanoparticles within high-surface area solid-state supports. This work will be important for the development of highly efficient industrial catalysts which give minimal undesired products, as well as solid-state sensors which can detect trace amounts of toxic gases in the atmosphere.
