NdO-SiO nanocomposites with enhanced photocatalytic activity have been obtained through simple and rapid sonochemical route in presence of putrescine as a new basic agent, for the first time. The influence of the mole ratio of Si:Nd, basic agent and ultrasonic power have been optimized to obtain the best NdO-SiO nanocomposites on shape, size and photocatalytic activity. The produced NdO-SiO nanocomposites have been characterized utilizing XRD, EDX, TEM, FT-IR, DRS and FESEM. Application of the as-formed NdO-SiO nano and bulk structures as photocatalyst with photodegradation of methyl violet contaminant under ultraviolet illumination was compared. Results demonstrated that SiO has remarkable effect on catalytic performance of NdO photocatalyst for decomposition. By introducing of SiO to NdO, decomposition efficiency of NdO toward methyl violet contaminant under ultraviolet illumination was increased.
首次通过简单快速的声化学路线，在腐胺作为一种新型碱性试剂存在的情况下，获得了具有增强光催化活性的NdO-SiO纳米复合材料。优化了Si:Nd的摩尔比、碱性试剂和超声功率的影响，以获得在形状、尺寸和光催化活性方面最佳的NdO-SiO纳米复合材料。利用XRD、EDX、TEM、FT-IR、DRS和FESEM对制备的NdO-SiO纳米复合材料进行了表征。比较了所形成的NdO-SiO纳米结构和块状结构作为光催化剂在紫外光照射下对甲基紫污染物进行光降解的应用。结果表明，SiO对NdO光催化剂的分解催化性能有显著影响。通过将SiO引入NdO，NdO在紫外光照射下对甲基紫污染物的分解效率提高。
