Fabrication of novel flower-like Sr3(VO4)2 anchored on g-C3N4: Visible-light-triggered degradation of organic contaminants

Herein, designing of sustainable flower-like novel Sr-3(VO4)(2)/g-C3N4 (SrVO/CN) nanocatalyst was successfully fabricated by easier hydrothermal method and utilised as a visible-light-driven for the degradation of methylene blue (MB) dye and ciprofloxacin (CF) antibiotic for the first time. The physicochemical behaviour of the nanocomposite was confirmed by various analytical techniques. These results confirm the successive development of flower-like Sr-3(VO4)(2) anchored on the g-C3N4 layer. The SrVO/CN can serve as an excellent catalyst for the decomposition of MB dyes and CF drugs under visible light irradiation. The results from UV-Vis spectroscopy evidently showed that the catalytic efficiency of SrVO/CN nanocomposite is higher than pure Sr-3(VO4)(2) nano-flowers. The SrVO/CN nanocomposite explores degradation efficiency of about 88.20% and 92.50% for MB and CF drug respectively. Furthermore, the stability and recycle behaviour of the SrVO/CN nanocomposites exhibit excellent effects. Hence, as prepared SrVO/CN behave as an example of the 'Killing of two birds with one arrow' approach.
