| 1 | 2024 Thesis | A facile surfactant-assisted synthesis of graphene oxide/zinc oxide catalyst for the degradation of methylene blue dye Mior Mohd Hasri Abdul Aziz This research aimed to study the role and the stabilization mechanism of hybrid photocatalyst comprising surfactant-exfoliated graphene oxide (sEGO) with zinc oxide (ZnO) for methylene blue (MB) removal. Graphite sheet was exfoliated to produce sEGO by employing synthesized triple chain anionic surfactant, sodium 1,4- bis(neopentyloxy)-3-(neopentylcarbonyl)-1,4-dioxobutane-2-sulfonate (TC14) and compared with commercially available sodium dodecyl sulphate (SDS). The structure, interfacial and colloidal stability of surfactant were studied using proton nuclear magnetic resonance (1H NMR) spectroscopy, air-water (a/w) surface tension and zeta potential measurement. The morphology of photocatalyst were characterized using Field emission scanning electron microscopy (FESEM), Raman spectroscopy, Highresolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The performance of photocatalyst for MB removal were measured through ultraviol..... 135 hits |
