以硝酸铅和钨酸钠为原料，环糊精作为表面活性剂，利用室温水溶液法制备出了海参状 PbWO4微晶。用粉末 X 射线衍射(XRD )、X 射线能谱仪(EDX)、扫描电子显微镜(SEM)等技术对样品进行了表征。通过对实验条件的探索，发现反应温度、pH 值及表面活性剂的浓度等对产物的形貌有较大的影响，并且提出了海参状微晶的3步形成机理。此外，探索了所制样品的光催化性能，发现其对罗丹明有很好的光催化降解效果。

Trepang-like PbWO4 microcrystals had been prepared by an aqueous solution method at room temper-ature with Pb(NO3 )2 and Pb(NO3 )2 as raw materials andβ-CD as surfactant.The products were characterized by powder X-ray diffraction (XRD),energy-dispersive X-ray spectrometry (EDX),scanning electron microsco-py (SEM).The effects of reaction conditions have also been investigated,which showed that the reaction tem-perature,pH and the concentration of surfactant have great influence to the morphology of products.A three-step formation mechanism was proposed.Besides,the photocatalytic performance of the products were studied which exhibited good photocatalytic effect toward rhodamine.
