Photochromic property of cerium oxide nanoparticles prepared by dialysis of solution of cerium nitrate

Results in Chemistry, 2022
CeO2 nanoparticles were obtained by heating 50 mL of 0.1 M Ce(NO3) 3·6H2O solution mixed with 5 mL of 1 M NH3 aq. at 368 K for 24 h. When H2O and ethanol were used as solvents for cerium nitrate hydrate, obtained CeO2 nanoparticles were aggregated.
