Abstract:
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.
