A high-flux, photocatalytic wood-derived filter for high-efficiency water purification.

Wastewater purification has evolved into a global problem in the face of increasing scarcity of freshwater resources. Photocatalysis technology possesses prominent advantages in treating pollutants in water because of its low cost and mild reaction conditions, which provides an effective way to treat multiple pollutants and reduce membrane fouling. Herein, we combine photocatalysis technology with filtration technology via in situ reduction Bi with BiSiO strategy incorporating a carbonized wood filter to synthesize carbon/BiSiO@Bi bi-functional composite.
