Environmental pollution poses a pressing global challenge, demanding innovative solutions for effective pollutant removal. Photocatalysts, particularly titanium dioxide (TiO2), are renowned their catalytic prowess; however, they often require ultraviolet light activation. Researchers had turned to doping with metals and non-metals extend utility into the visible spectrum. While this approach shows promise, it also presents challenges such as material stability dopant leaching. Co-doping, involving both non-metals, has emerged viable strategy mitigate these limitations. Inthe fieldof adsorbents, carbon-based materials doped nitrogen gaining attention improved adsorption capabilities CO2/N2 selectivity. Nitrogen enhances surface area fosters interactions between acidic CO2 molecules basic functionalities.

In this study, graphene oxide (GO), ZnO nanoparticles (NPs) and GO based nanocomposites (GO-ZnO) have been successfully synthesized by modified Hummer's method, chemical co-precipitation method ultrasonication respectively. Powder X-ray diffraction (PXRD), transmission electron microscopy (TEM) Fourier transform infrared (FTIR) spectroscopy were employed to study the crystallographic structure, phase, surface micro-morphology different functional groups in prepared catalysts. The optical band gap of pristine NPs was found UV region (3.2 eV), whereas immobilized on nanosheets possesses it visible wavelength (2.67 eV). GO-ZnO catalysts demonstrate excellent degradation efficiency (97.7 %) within just 85 min due its effective adsorption light driven photocatalytic activity rhodamine B (RhB) dye. capacity ∼ 24 times higher with second order kinetic rate constant as low 0.0014 ∙ g/mg 9 faster when compared unmodified catalyst. Effect catalyst dosages RhB also conducted. scavenger test firmly evidenced that super radicals (•O2–) play lead role dye process nanocomposites. Reusability studies more than 91 % up 4 back-to-back cycles along retaining crystal structure. These findings suggest viable application for wastewater.
