中文摘要：

利用制浆造纸废料木质素磺酸钠为结构导向剂，采用直接沉淀法制备了纳米氧化锌材料。使用XRD、SEM和氮气吸附-脱附实验对所合成的氧化锌进行了表征。XRD分析结果揭示产物为高结晶度的多晶六方纤维锌矿氧化锌；SEM和氮气吸附-脱附实验分析表明使用的木质素磺酸钠的量不同，制备的氧化锌形貌和比表面积不同，在一定范围内增加木质素磺酸钠用量可以增加ZnO的比表面积。

英文摘要：

Nano-ZnO crystals were prepared by direct method with the help of structure directing agent of lignosul- phonate, which is a byproduct of pulp industry. The X-ray diffraction （XRD） ,SEM and Nitrogen adsorption-desorption experiments are used to characterize as-prepared ZnO crystals. XRD studies showed that fine hexagonal wurtz- ite ZnO particles with high crystallinity can be obtained. Studies on SEM and nitrogen adsorption-desorption experi- ments revealed that different concentrations of lignosulphonate can affect the morphology and specific surface area of ZnO. Specific surface area of ZnO will increase when more lignosulphonate are used during preparation.
