Abstract
So far, the application of inorganic glass materials in the field of photocatalysis has not been explored. First, phase separation induced CsPbBr3 quantum dot glasses, as an unprecedented method, is proposed in this work. The results show that the fluorescence intensity of quantum dots (QDs) glass is increased by 1.5 times compared with the initial intensity after the thermal cycle, showing excellent thermal stabilities. Furthermore, the quantum dots glass material is used for the first time in antibiotic residues degradation. The concentration of TC-HCl in 20 mg/L is degraded by 73% in 1 h, and the photocatalytic efficiency reaches 85% of the initial value after three cycles, revealing favorable water stabilities. In this paper, quantum dot glass material breaks the inherent thinking of the preparation methods, and it explores the feasibility application in fields of photocatalyst and brings unexpected changes to the application of glass material in the future.
