本文采用聚丙烯酰胺凝胶法合成了YMn2O5纳米粒子。结果表明,采用不同的螯合剂,可以制备出尺寸均匀、形状接近球形的高质量YMn2O5纳米粒子。然而,发现产物的平均粒径依赖于螯合剂的选择。使用柠檬酸作为螯合剂制备的样品具有约45nm的平均粒度,而通过使用螯合剂EDTA制备的样品具有以70nm为中心的粒度。从光吸收测量中得到柠檬酸和EDTA产生的样品的光学能带隙分别为1.21和1.17eV。光催化实验表明,所制备的YMn2O5纳米粒子在紫外光和可见光照射下对甲基红的氧化降解具有良好的光催化活性.
In this work, a polyacrylamide gel route is introduced to synthesize YMn2O5nanoparticles. It is demonstrated that high-quality YMn2O5nanoparticles with a uniform size and spherical shape can be prepared using different chelating agents. However, the average particle size of the products is found to have a dependence on the choice of the chelating agent. The sample prepared using citric acid as the chelating agent has an average particle size of ~45nm, while the sample prepared by using the chelating agent EDTA has a particle size centered around 70nm. The optical energy bandgap of the citric acid- and EDTA-resulted samples is obtained, from optical absorption measurements, to be 1.21 and 1.17eV, respectively. The photocatalytic experiments reveal that the as-prepared YMn2O5nanoparticles exhibit an interesting photocatalytic activity for oxidative decomposition of methyl red under ultraviolet and visible-light irradiation.
