Synthesis Metal-Organic Framework (MOFs) Cr-PTC-HIna Modulated Isonicotinic Acid for Methylene Blue Photocatalytic Degradation

A novel responsive visible light Cr-based MOF, Cr-PTC-HIna, was synthesized using the solvothermal method. Cr-PTC-HIna peaks were observed at 2 theta = 9.04 degrees, 12.71 degrees, 14.88 degrees, 25,48 degrees, 27.72 degrees, 28.97 degrees, and 43.60 degrees with a crystal size of 21 nm. Band gap energy achieved from the Cr-PTC HIna was 2.05 eV. Scanning Electron Microscope (SEM) analysis obtained a 3D structural morphology of MOFs Cr-PTC-HIna with a cylindrical tube shape and a particle size of 251.45 nm. Cr-PTC-HIna gave the optimum methylene blue degradation at pH of 7 under 250 watts mercury lamp irradiation for 180 minutes with degradation capacity of 95.40 mg/g. Electron holes and hydroxyl radicals were found as the dominant species contributing to methylene blue degradation. Copyright (c) 2022 by Authors, Published by BCREC Group.
