Synthesis of a novel one-dimensional Bi2O2CO3–BiOCl heterostructure and its enhanced photocatalytic activity

A novel one-dimensional Bi₂O₂CO₃–BiOCl heterostructure was synthesized. BiOCl nanosheets uniformly and vertically grew onto the Bi₂O₂CO₃ porous rods via crystallographic oriented epitaxial nucleation and growth. Bi₂O₂CO₃–BiOCl displayed excellent photocatalytic activity.
