摘　　要：模板法制备氧化亚铜(Cu_(2)O)是一种高效合理、切实可行的手段,应用前景十分广阔。以Cu_(2)(CH_(3)COO)_(4)和NaOH为原料制备Cu(OH)_(2),利用葡萄糖将Cu(OH)_(2)还原成Cu_(2)O为制备原理,在模板剂十二烷基硫酸钠(SDS)和氧化石墨烯(GO)的调控下,利用其空间限域效应将反应物限制在有限空间内去控制目标产物的成核与生长,以此来达到对晶体大小、形貌和结构的精准调控,同时可以实现将Cu_(2)O(SDS)负载于GO表面形成Cu_(2)O/GO(SDS)复合催化剂。利用X射线衍射(XRD)和扫描电镜(SEM)技术对材料进行了形貌结构表征,以有机染料亚甲基蓝(MB)为目标污染物,评估了材料的光催化性能。实验结果表明,相较于Cu_(2)O、Cu_(2)O(SDS)和Cu_(2)O/GO,Cu_(2)O/GO(SDS)表现出最佳的光催化效率,MB的降解率和降解速率均有显著提升。The template method for preparing cuprous oxide(Cu_(2)O) is an efficient,practical,and feasible approach with broad application prospects.In this study,Cu(OH)_(2) was synthesized from Cu_(2)(CH_(3)COO)_(4)and NaOH,which was subsequently reduced to Cu_(2)O by glucose.By employing sodium dodecyl sulfate(SDS)and graphene oxide(GO)as a template agent,the spatial confinement effectively restricted the reactants to a limited space,allowing for precise control over the nucleation and growth of the target product,thereby achieving control over the crystal size,morphology,and structure.Following this,Cu_(2)O(SDS)was also loaded onto the surface of GO to form the Cu_(2)O/GO(SDS)composite catalyst.The materials were characterized by X-ray diffraction(XRD)and scanning electron microscope(SEM).Methylene blue(MB),an organic dye,was used as the target pollutant to evaluate the photocatalytic performance of the materials.The results indicate that Cu_(2)O/GO(SDS)exhibited superior photocatalytic efficiency compared to Cu_(2)O,Cu_(2)O(SDS),and Cu_(2)O/GO,with significantly enhanced degradation rates for MB.This study offers new insights and methods for designing efficient and environmentally friendly catalytic materials,which is of great significance for advancing the fields of environmental science and nanotechnology.
