Fluorescent Scandium Microspheres for Highly Efficient White‐Light Photocatalysis

Abstract Efficient photocatalysts play an important role in the various fields such as pollutant treatment and the generation of clean energy. Therefore, developing a photocatalyst with high activity is of great significance. Herein, scandium‐based fluorescent microspheres (Sc‐FMs) are facilely prepared through the one‐pot hydrothermal polymerization of scandium ions and tartaric acid. The prepared Sc‐FMs show strong blue solid‐state fluorescence, with a maximum emission at 412 nm. Meanwhile, Sc‐FMs possess a strong white‐light photocatalysis ability, which can be used for the photodegradation of dye pollutants (rhodamine 6 G) under low power white light without the assistance of any radical generating agents. In addition, the Sc‐FMs display good stability and recyclability. As a result, this new and efficient Sc‐FMs photocatalysts hold a promise for potential applications in environmental treatment.
