Abstract

We report a single-particle approach for studying the photocatalytic oxidation reaction on individual anatase TiO₂ particles. Single-particle kinetic and imaging analyses of the chemiluminescence (CL) emitted from the probe dye molecules revealed that the oxidation reactivity is not significantly dependent on the crystal faces.
