The present review covers the outline of the application of photoluminescence (PL) spectroscopy to understand the photocatalytic reactions on the bulk semiconducting materials and highly dispersed metal oxide single-site heterogeneous catalysts at their working states. The first part focuses on the applications of PL spectroscopy to elucidate the surface active sites and surface band structures of the inorganic and organic bulk semiconducting photocatalysts at their working states. The second part describes the applications of in situ PL spectroscopy to elucidate the surface active sites of the highly dispersed metal oxide single-site heterogeneous catalysts and their roles in photocatalytic reactions at the molecular level. The last part is a brief conclusion and future direction of PL studies.
