3D-FDTD is used to compute the electromagnetic response of various plasmonic nanostructures. Results of
computation and simulation are used to design the contact area of the photo-catalytic reactors. Novel nano-fabrication
techniques are developed to implement large surface area of plasmonic nanostructures for photo-catalytic reactors.
Measurement and analysis of the photo-catalytic process happened in the newly designed photo-chemical reactors clearly
demonstrate better efficiency of some photo-catalytic chemical process such as the decomposition of the Methyl Orange
to carbon dioxide and water.
