Photodegradation of Methylene Blue by TiO₂

概述

TiO₂ photocatalysis generates hydroxyl radicals and superoxide ions that mineralize organic pollutants like methylene blue into CO₂, water, and simple inorganic ions. Methylene blue serves as a standard test dye for evaluating photocatalyst performance because its degradation is easily tracked by its visible blue color fading.
