Abstract: Zinc oxide (ZnO) is considered as a potential material among metal oxide semiconductors. However, the setbacks of the ZnO can be corrected using non-metal doping on ZnO. Nitrogen is considered as a promising candidate for doping because of similar atomic radius and lower ionization energy and electronegativity creates a shallow acceptor level in ZnO. Herein, we have successfully synthesized Nitrogen doped ZnO (ZnO: N) using pulsed laser assisted technique in various concentration of urea solution. The synthesized material were characterized using HR-TEM, FE-SEM, XRD, UV-Visible, Micro-Raman and Photoluminescence spectra. As prepared material treated for the degradation of tetracycline under visible light illumination (VLI). The photocatalytic activity (PCA) of ZnO: N performed on an antibiotic tetracycline pollutant .The ZnO: N nanomaterial showed higher degradation of TC than pristine ZnO. Hence, Nitrogen doping helps in changing intrinsic characteristics of the material. The excited electron is trapped in the accepter level of nitrogen. Hence; induced charges are separated and helps in generation of reactive oxygen species (ROS). The ZnO: N nanomaterial has same potential applications as of ZnO. Our work provides a rational design of photocatalyst for environmental remediation.
