摘要
采用水热法,以Pb(NO_3)_2和K_2S_2O_8为原料,十二烷基苯磺酸钠(SDBS)为表面活性剂,在碱性溶液中制备纯相的β-PbO_2微米球。利用粉末X射线衍射仪(XRD)和扫描电子显微镜(SEM)对所得产物进行分析表征,并考察表面活性剂对其形貌的影响。以聚乙烯吡咯烷酮(PVP)为表面活性剂时可得到微米空球。
With Pb（NO3 ）2 and K2S2O8 as raw materials,and sodium dodecyl benzene sulfonate（SDBS） as the surfactant,pure β-PbO2 microspheres are prepared by the hydrotherrnal method in the alkaline solution. The products are characterized using the X-ray diffraction（XRD） and scanning electron microscopy（SEM）. The effect of the surfac- rant on the morphology is also investigated. The micrometer hollow spheres are prepared with poly（vinyl pyrrolidone） （PVP） as the surfactant.
