Link) Leaves Extract: Characterization and Photocatalytic under Visible Light Irradiation JF - Jurnal Penelitian Pendidikan IPA JA - jppipa, pendidikan ipa, fisika, biologi, kimia VL - 8 IS - 4 SE - Research Articles DO - 10.29303/jppipa.v8i4.1764 UR - https://jppipa.unram.ac.id/index.php/jppipa/article/view/1764 SP - 1759-1763 AB - <p>CeVO<sub>4 </sub>as visible light driven photocatalyst was synthesized using <em>Senna occidentalis (L.) Link</em> leaves extract <em>(SOE) </em>by sol-gel method which can increase the degradation of malachite green (MG) under visible irradiation. The products were characterized using Fourier Transform Infrared Spectrophotometer (FTIR), X-ray Diffraction (XRD), and Field Emission Scanning Electron Microscope Energy Dispersive Spectroscopy (FESEM-EDS). UV–Vis Diffuse Reflectance Spectrophotometer (UV–Vis DRS) absorption spectrum indicated that the band gap of the CeVO<sub>4</sub> is about 2,76 eV, and XRD patterns of the samples were indexed to tetragonal zircon type CeVO<sub>4 </sub>structure. Photocatalytic activity of the synthesized CeVO<sub>4</sub> nanoparticles was evaluated for degrading the MG under visible light irradiation, showing as an active catalyst on photodegradation of the MG up to 77% under experimental condition of this study.</p> ER -
