Synthesis of Bimetallic Metal-Organic Frameworks (MOFs) La-Y-PTC for Enhanced Dyes Photocatalytic Degradation

Metal-Organic Frameworks (MOFs) is widely utilized as photocatalysts in dye photocatalytic degradation. This study successfully synthesized bimetallic MOFs La-Y-PTC by the solvothermal method. The synthesized La-YPTC has a diffractogram pattern with a value of 2 theta = 5.69 degrees; 9.57 degrees; 16.8 degrees; 20.05 degrees; 24.8 degrees; 26.15 degrees; 29.77 degrees and 41.93 degrees with a crystal size of 21.45 nm. The La-Y-PTC has symmetric and asymmetric (COO-) at 1591 and 1433 cm-1, La-O and Y-O groups at 596 and 659 cm-1 and a band gap energy of 2.16 eV. Scanning Electron Microscope analysis showed that the morphology of La-Y-PTC is spherical with a particle size of 354.307 nm. La-Y-PTC degrades methylene blue and methyl orange at pH 2 with a degradation efficiency of 69.57% and 93.63%, respectively, under 250 watts of mercury lamp irradiation for 180 min with hydroxyl radical species as a dominant species that play a role in methylene blue and methyl orange degradations.
