Ultrathin graphitic carbon nitride (U-g-C3N4) is prepared by exfoliation of bulk g-C3N4 used as an adsorbent for aqueous Ce3+ adsorption. Adsorption capacity of U-g-C3N4 is found to be influenced by initial concentration, solution pH, contact time and temperatures (288K to 313K). Adsorption kinetics is studied by using both pseudo first and second order kinetic model. Initial and Ce accumulated U-g-C3N4 are characterised by X-ray diffraction (XRD), UV-visible, Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy for optical properties and scanning electron microscopy (SEM) for morphological behaviour. Valence band of C1s, N1s and Ce3d are observed through X-ray photoelectron spectroscopy (XPS). Specific surface area is measured by BET analysis. AFM profile shows that the average thickness of two dimensional sheets has increased after adsorption. Defects due to lattice disorientation are found in high resolution transmission electron microscope (HR-TEM). Photo catalytic dye degradation efficiency reaches upto 95% under sunlight irradiation.
