In Fig. 1b and c, the tourmaline exhibits a bulk morphology, while Bi2WO6 exhibits a lamellar structure (Fig. 1d), facilitating the good adhesion of tourmaline to its surface. This observation is reconfirmed in Fig. 1e, where tourmaline is uniformly distributed on the surface of Bi2WO6. Besides, the TEM (Fig. 1f) and HRTEM (Fig. 1g) were employed to investigate the finer microstructure of the T/BWO composite material. In the TEM image of 40 %T/BWO, the black regions indicate the existence of

Bismuth tungstate (Bi2WO6) has been renowned for its affordability, non-toxic nature, and outstanding performance, but rapid carrier recombination has always been its fatal drawback. However, the inherent surface electric field of tourmaline effectively reduces carrier recombination and promotes their rapid separation. Consequently, the successful preparation of tourmaline/Bi2WO6 (T/BWO) composite materials has been achieved. Characterization and experiments indicate that, under the influence of the tourmaline electric field, the photocatalytic performance of Bi2WO6 is significantly enhanced. ...
