Hierarchical Ag/Bi2MoO6 hollow nanoboxes with high photocatalytic performance.

Well-ordered hierarchical Ag/Bi2MoO6 hollow nanoboxes are obtained through an artful hydrothermal method. Ag3PO4 nanocubes serve as growth templates and precursor sources of Ag. Ag3PO4 is reduced to Ag nanoparticles, which are dispersed on the nanosheet-built hierarchical Bi2MoO6 nanoboxes. With the investigation of intermediate products, the growth process of Ag/Bi2MoO6 is studied. Due to the hierarchical hollow structure and the introduction of Ag, the Ag/Bi2MoO6 nanoboxes exhibit enhanced visible-light absorption and photocatalytic performance compared to the pristine Bi2MoO6 microboxes.
