•Bi2MoO6 3D-flower-like nanostructure was prepared by mechanochemical reaction.•Acetamide directed solid phase reaction towards producing this special morphology.•High photocatalytic ability was observed for removal of some organic dye pollutants.
In this work, we successfully prepared 3D hierarchical flower-like nanostructure of Bi2MoO6 by a facile mechanochemical reaction followed by heat treatment at 450°C for 2h. The used all chemicals were low-cost and environmentally benign compounds. Acetamide/NH4NO3 was used as driving/oxidizer agent to direct the solid phase reaction towards producing special morphology in nanoscale. Characterization results revealed that the resulting compound has been arranged from a 3D hierarchical structure with an ornamental cabbage-like shape composed of nanoparticles. The influence of milling time on the morphology growth was studied via running mechanochemical reaction in the milling time from 30 to 120min. The photocatalytic property of this product was studied for the removal of some organic dye pollutants in water under light irradiation. The results revealed a high degree of photodegradation capability, which can be related to its special structure, more active sites and high light-harvesting capacity.
