Abstract : Universiti Pendidikan Sultan Idris

In this work, sand/zinc oxide (ZnO) nanorods (NRs) have been successfully fabricated on the sand particles using the sol-gel immersion method.The sand/ZnO NRs/custom made immersion methods have successfully composited tri-chain hyper-branched (TC14) ? graphene oxide (GO) and sand/ZnO NRs/sodium dodecyl sulfate surfactant (SDS) ? GO. The FESEM images show the sand/ZnO NRs/TC14-GO have the thin layer compare to sand/ZnO NRs/SDS-GO. The structural properties of sand/ZnO NRs/TC14-GO and sand/ZnO NRs/SDS-GO investigated by Micro-Raman Spectra. Which the sand/ZnO NRs/TC14-GO show best crystallinity compare to sand/ZnO NRs/SDSGO based on ID/IG ratio was around ~ 0.81 and 0.23. The photocatalysis performance were investigated by UV-vis instrument under 365 nm. The highest removal percent of 5 parts per million (ppm) of methylene blue (MB) with 30 g were observed in sand/ZnO NRs/TC14-GO after 72 hours was ~100%. The improvement of photocatalysis performances of sand/ZnO NRs by composited with GO have been explained by the mechanism. ? 2021 Trans Tech Publications Ltd, Switzerland.
