摘要: A three-step route has been adopted for the synthesis of AgBr quantum dots coupled porous BiOBr spheres. Firstly, Bi spheres were obtained through a simple solvothermal method employing ethylene glycol as reducing agent. Sequentially, redox reaction with NH4Fe(SO4)2 an oxidiser was employed to prepare Finally, loaded on in situ precipitation. The powders characterised by powder X-ray diffraction phase confirmation and transmission electron microscopy microstructure evolution. hierarchical diameter ca. 500 nm made up two-dimensional nanosheets. deposited petals did not influence morphology host. BiOBr/AgBr composite exhibited higher photocatalytic activity than pure degrading Rhodamine B dyes.
