摘要：Silver tungstate (Ag2WO4) multilevel sphere clusters were synthesized for the first time by a dynamic-template route through controlling the energy distribution on the crystal surface. The polymerization reaction of acrylamide monomers as the dynamic-template on the surface of the Ag2WO4 crystals occurred, with more polymerization causing more high energy spots to appear on the surface of the Ag2WO4 crystals, and the change of energy caused by this affected the formation and growth of the multilevel sphere clusters. The Ag2WO4 multilevel sphere clusters were 2.5-2.8 mu m in diameter and constituted several second level spheres which were about 0.8 mu m in diameter. The XRD patterns indicated that the Ag2WO4 products were perfectly matched with the hexagonal-phase Ag2WO4 crystal system and the symmetric space type belonged to the P6(3) symmetric system. In addition, the Ag2WO4 products had good visible light photocatalytic performance and antimicrobial ability.
