摘要: Abstract Monoclinic Li2MnO3 nanostructures were synthesized via modified Pechini sol-gel approach employing the mixture of metal cations, ethylene glycol and different chelating agents. By changing variables experimental conditions including molar ratio M:EG:CA, pH type agent can control shape size nanostructures. In order to confirmation crystalline structural features, XRD, FT-IR EDX analyses carried out. SEM TEM images taken for morphology investigation. Band-gap nanoparticles calculated by UV–Vis data is 1.76 eV. Moreover, photocatalytic activity nanoparticle was investigated nano bulk structures in aqueous solution visible light degradation two dyes acid red 88 malachite green. Some effective parameters such as dye type, catalyst dosage, structure cationic additives evaluated optimum removal water pollutant dyes. Cationic have behaviors against anionic
