Abstract

In an experiment investigating the photo catalytic degradation of methylene blue using varied concentrations of Er2O3 nanoparticles, different conditions were tested including with and without sunshine, as well as in the absence of a UV source. The presence of a UV source was also considered in the research. UV-Visible spectroscopy was utilized to characterize the catalysts. The degradation of methylene blue dye was monitored by spectrophotometry by tracking dye absorbance at regular time intervals and adjusting the dye concentration. The results indicated that the most effective degradation of methylene blue dye occurred during a 5-hour irradiation time and in the presence of a UV source. The study also discussed the characterization of Er2O3 nanoparticles.
