Abstract Scope |
In the current study, gadolinium ions accumulated two-dimensional graphitic carbon nitride (Gd3+-2D-g-C3N4) is synthesized through a single-step chemical adsorption methodology. This chemisorption causes 2D planar defects incorporation in Gd3+-2D-g-C3N4, as confirmed through the X-ray diffraction (full width at half maximum (FWHM)) and high-resolution transmission electron microscopy studies. The thickness of Gd3+-2D-g-C3N4 is also increased from 6 nm to 9 nm in the atomic force microscopy thickness profile. Gd3+-2D-g-C3N4, as compared to 2D-g-C3N4, depicts fine-tuned band gap energies (Eg; 2.81 to 1.83 eV), modified specific surface area (SBET; 69.12 to 109.8 m2/g), and increased Raman intensity ratio (ID/IG; 0.72 to 1.05). Furthermore, the piezo-photocatalytic applicability of Gd3+-2D-g-C3N4 is further checked with antibiotic kanamycin sulfate (KS) remediation. The remediation efficiency for Gd3+-2D-g-C3N4 has increased up to 24% (89% in 120 min) compared to pristine 2D-g-C3N4. KS remediation is further confirmed through HPLC and LC-MS analyses. |
