Biomimetic Guided Bi₂WO₆/Bi₂O₃ Vertical Heterojunction with Controllable Microstructure for Efficient Photocatalysis.

ABSTRACT: To bridge the technical gap of heterojunction induction control in conventional semiconductor photocatalysts, a method of regulating the growth of heterojunctions utilizing biomimetic structures was designed to prepare a series of Bi₂WO₆/Bi₂O₃ vertical heterojunction nanocomposites for the disposal of environmentally hazardous tetracycline wastewater difficult to degrade by conventional microbial techniques. Porous Bi₂O₃ precursors with high-energy crystalline (110) dominant growth were produced using the sunflower straw bio-template technique (SSBT). Bi₂WO₆ with a (131) plane grew preferentially into 2.8 to 4 nm pieces on the (110) plane of Bi₂O₃, causing a significant density red
