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（ZnIn2S4）原位负载于纸浆纤维（PFs）上，制得ZnIn2S4/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ZnIn2S4被成功负载于PFs上，紫外-可见漫反射光谱（UV-Vis DRS）分析表明ZnIn2S4/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，ZnIn2S4/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ZnIn2S4/PFs复合纸的甲醛去除率最高（73.14%）。将ZnIn2S4/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ZnIn2S4/PFs复合纸具有很好的环境稳定性。ZnIn2S4/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。
Abstract: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 （ZnIn2S4） was loaded on pulp fibers （PFs） in situ to prepare ZnIn2S4/PFs composite paper， and its photocatalytic performance for formaldehyde removal was explored. The successful loading of nano ZnIn2S4 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 ZnIn2S4/PFs composite paper had photocatalytic activity. It was found that the formaldehyde removal rate of ZnIn2S4/PFs composite paper first increased and then decreased with the increase of indium nitrate dosage. The formaldehyde removal rate of the prepared ZnIn2S4/PFs composite paper reached the highest （73.14%） when indium nitrate dosage was 4 mmol. The tensile index of ZnIn2S4/PFs composite paper only decreased by 5.1% when it was placed in the natural environment for 30 days， illustrating the ZnIn2S4/PFs composite paper was of very good environmental stability. The formaldehyde removal rate of ZnIn2S4/PFs composite paper decreased by 26.94% after three photocatalytic cycles， it showed that it had good recycling performance.
