Preparation of large-faced flower-like Bi2WO6 using carbon as a template to enhanced photocatalytic activity under visible light

Sewage treatment is a critical issue that needs to be resolved urgently. Accordingly, in this study, a large-faced flower-like Bi2WO6 was prepared via a one-step hydrothermal method using corncob biomass carbon as the carrier; subsequently, its structure and morphology were characterized. The results showed that the as-prepared material exhibited good dispersion properties. Rhodamine B (RhB) and tetracycline (TC) were used as simulated pollutants to detect the photocatalytic activity of the prepared materials. The experimental results showed that Bi2WO6 modified with C demonstrated a good catalytic performance to pure Bi2WO6. Furthermore, it also exhibited excellent stability, the removal rates of RhB and TC reached 98% and 87%, respectively. The proposed material is expected to be of significant application value in the field of wastewater treatment.
