    Synthesis and Characterization of COF based Nanocomposites as Photocatalyst
    (Library Information Services COMSATS University Islamabad Lahore Campus, 2023-02-26) Talha Rafi; FA21-R06-027; Dr. Muhammad Shahid Nazir; LHR TP 8457
    Dyes are synthetic organic compounds that are abundantly used in industries. The use of these dyes is major contributors towards environmental pollution. Their hazardous nature raises great concerns in general public. Advancement in nanotechnology can efficiently help in mitigating this problem as nanoparticles can efficiently convert these harmful dyes into less harmful chemical byproducts through a process called Photocatalysis. COF has been reported as photocatalyst with less stability and efficiency. In this paper, new modification of COF-LZU-1 was reported by dopping Cu, Zn, Fe and Ag metals into COF-LZU-1 nanoparticles by simple solvothermal method. Degradation of 40ppm methylene blue and congo red dye was reported by adding 2mg of each metal modified COF-LZU-1. Cu being and excellent photocatalyst with smallest bend gap of 2.1eV, degraded Congo Red dye (95.7%) and Methylene Blue dye (80%). All these metals do not change actual structure of COF-LZU-1 but enhanced photocatalytic activity of COF-LZU-1.
