摘要

We present the first evidence for the synthesis of nanotwinned polyhedral 26-facet Cu7S4 microcages enclosed within polycrystalline shells. The photocatalytic superiority of these cages is attributed to the presence of a larger number of nanotwinned building blocks, which exhibited higher adsorption ability and catalytic activity for enhancing photodegradation of methylene blue (MB) dye.
