摘　　要：Zn（OH）F microbesoms have been synthesized on a large scale by a facile solution-based method using polymer as crystal growth modifier. The obtained products were characterized by X-ray powder diffraction （XRD）, X-ray photoelectron spectroscopy （XPS）, and scanning electron microscopy （SEM）. The effects of modifier polyacryla- mide （PAM）, reaction time, concentrations of NaF on the morphology and size of the product were studied. The resuits revealed that the Zn（OH）F microbesom had orthorhombic structures. Experimental conditions had all influence on the shape and size of the final products, but polymer PAM played the key role in formation of the Zn（OH）F microbesom. This novel structures exhibited good UV photocatalytic abilities,Zn（OH）F microbesoms have been synthesized on a large scale by a facile solution-based method using polymer as crystal growth modifier.
