Summary

My previous background was mainly based on providing molecular level insight regarding adsorption and desorption properties and mechanisms of exhaust gas molecules (i.e. NO, NO2, SO2, CO, CO2, NH3) on oxide surfaces and elucidating the structure functionality relationships of complex ternary/quaternary mixed oxides via in-situ Fourier Transform Infrared Spectroscopy (in-situ FTIR), Temperature Programmed Desorption (TPD) and benchtop diffraction and imaging techniques. In addition to these detailed in-situ spectroscopic studies on catalytic powders, quantitative NOx storage capacities of the synthesized materials prepared in a monolithic form were also investigated using a flow reactor operated under realistic catalytic conditions. Moreover, kinetic rate analysis were performed under flow regime for different oxidation reactions such as NO, CO and NH3 oxidation for exhaust-cleaning application. My current research interest is Nanofabrication, nanofluidics and nanoplasmonics and applications of nanofluidics structures decorated with individual catalyst nanoparticles for the purpose of developing an IR-microscopy based scheme for the detection of reaction products and adsorption chemistry on individual nanoparticles.
