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.
