Anion exchange strategy for construction of sesame-biscuit-like Bi2O2CO3/Bi2MoO6 nanocomposites with enhanced photocatalytic activity

Sesame-biscuit-like Bi2O2CO3/Bi2MoO6 nanoplatelets with adjustable content of Bi2O2CO3 were successfully prepared by a facile anion exchange method under hydrothermal treatment. The heterojuncted Bi2O2CO3/Bi2MoO6 nanoplatelets exhibited a 64-fold faster rate than the single Bi2MoO6 nanoparticles toward photocatalytic degradation of RhB.
