Designing a novel 3D structured PVP-assisted Bi-TDC coordination polymers catalyst with tunable bandgap structure to decompose dyes

Abstract

The exploration of an efficient porous hybrid materials is significant due to their unique properties and good development prospects in catalytic applications. Herein, the PVP-assisted 3D Bi-TDC (2,5-thiophene dicarboxylate acid) is designed by solvothermal reaction to capture solar and mechanical energy for the degradation of rhodamine B (RhB, 5 mg/L) and methylene blue (MB, 5 mg/L). The RhB and MB degradation of the PVP-assisted Bi-TDC reached 99.6 % and 90.2 % under the ultrasonic vibrations and photocatalysis, which displays a higher catalytic activity compared to the bare Bi-TDC. The obviously enhanced catalytic activity can be ascribed to the integrated of ultrasonic vibrations and photocatalysis, the efficient separation of electron-hole pairs and its uniform and regular structure. This present work provided a new strategy to develop a controllable structures and excellent catalytic material for the environmental and energy application.
