摘　　要：本研究以硝酸铟为铟源,硫代乙酰胺为硫源,硝酸锌为锌源,将硫化铟锌(ZnIn_(2)S_(4))原位负载于纸浆纤维(PFs)上,制得ZnIn_(2)S_(4)/PFs复合纸,对其光催化除甲醛特性进行了分析。X射线光电子能谱仪(XPS)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)分析表明ZnIn_(2)S_(4)被成功负载于PFs上,紫外-可见漫反射光谱(UV-Vis DRS)分析表明ZnIn_(2)S_(4)/PFs复合纸具有光催化活性。研究发现,随着硝酸铟用量的增加,ZnIn_(2)S_(4)/PFs复合纸的甲醛去除率先增加后降低。当硝酸铟用量4 mmol时,所制ZnIn_(2)S_(4)/PFs复合纸的甲醛去除率最高(73.14%)。将ZnIn_(2)S_(4)/PFs复合纸放置于自然环境中30天,其抗张指数仅下降了5.1%,说明ZnIn_(2)S_(4)/PFs复合纸具有很好的环境稳定性。ZnIn_(2)S_(4)/PFs复合纸经3次光催化循环后,甲醛去除率下降了26.94%,表明具有较好的循环使用性能。In this study,indium nitrate was used as the source of indium,thioacetamide as the source of sulfur,zinc nitrate as the source of zinc,nano indium zinc sulfide(ZnIn_(2)S_(4))was loaded on pulp fibers(PFs)in situ to prepare ZnIn_(2)S_(4)/PFs composite paper,and its photocatalytic performance for formaldehyde removal was explored.The successful loading of nano ZnIn_(2)S_(4) on PFs was confirmed by X-ray photoelectron spectroscopy(XPS),X-ray diffractometer(XRD),and scanning electron microscope(SEM).UV-Vis DRS analysis showed that the ZnIn_(2)S_(4)/PFs composite paper had photocatalytic activity.It was found that the formaldehyde removal rate of ZnIn_(2)S_(4)/PFs composite paper first increased and then decreased with the increase of indium nitrate dosage.The formaldehyde removal rate of the prepared ZnIn_(2)S_(4)/PFs composite paper reached the highest(73.14%)when indium nitrate dosage was 4 mmol.The tensile index of ZnIn_(2)S_(4)/PFs composite paper only decreased by 5.1%when it was placed in the natural environment for 30 days,illustrating the ZnIn_(2)S_(4)/PFs composite paper was of very good environmental stability.The formaldehyde removal rate of ZnIn_(2)S_(4)/PFs composite paper decreased by 26.94%after three photocatalytic cycles,it showed that it had good recycling performance.
