Abstract

This study numerically investigates the light absorption of a plasmonic photocatalyst in the circular plane waveguide of a photocatalytic spinning disk reactor. The degradation of methyl orange (MO) in water with a dual light source spinning disk reactor (DL-SDR) and embedded diffusion coupler demonstrates the plasmonic photocatalytic reaction. When light propagates in the circular plane disk (CPD) waveguide of a DL-SDR, it gradually loses energy because of the absorption of the photocatalyst. This absorption boosts the processing efficiency of the plasmonic photocatalytic reaction. A real case by a diffusion coupler was used to present the plasmonic photocatalytic reaction. This study presents the numerical analysis of a secondary optical lens (SOL) coupler and the numerical evaluation of light absorption of the plasmonic photocatalyst in a DL-SDR. An elliptical reflector collects the light emitted from the circular ring edge of the SOL and CPD. This study presents an evaluation method that simulates the light absorption of a photocatalyst coating on the CPD of a DL-SDR. © 2013 The Optical Society of Japan.
