Investigation of Catalytic and Photocatalytic Degradation of Methyl Orange Using Doped LaMnO3 Compounds

LaMnO3 and 1% Pd-, Ag-, or Y-doped perovskite type nanomaterials were prepared by the sol-gel method, followed heat treatment at a low temperature (600 °C for 6 h). The investigation through X-ray diffraction FT-IR spectroscopy indicated that all samples well crystallized, without secondary phases, transition metal doping changed crystal structure from R-3c space group undoped to Pm-3m doped compounds. In this research paper, efficiencies of materials methyl orange removal analyzed, wherein effect ions pH on catalytic activity studied together with kinetic approach different values pH. Moreover, in activity, it should be noted slightly better performance was obtained Ag-doped compared Y- Pd-doped samples. results presented reinforce interest these multifunctional used industrial applications; e.g., water treatment.
