  Dye degradation has been for more than forty years in the scientific
community. All these studies have primarily focused on breaking various dyes
using catalysts driven by either light or heat. Most studies started to focus
on metal-oxides after the discovery of water-splitting by TiO2. Among the many
catalysts used plasmonic metal nanostructures have been explored significantly
in recent times due to their special property called localized surface plasmon
resonances (LSPR). However, facing multiple problems of heat losses and
instability, people started to focus on dielectric medium-to-high refractive
indexed materials for photonic applications. Most of these dielectric materials
have been studied from a physics point of view and less from chemistry. In this
work, we have focused on how these materials can be used for tuning selectivity
through wavelength-dependent studies by performing methylene blue (MB) dye
degradation.
