Sintesis Komposit Zno/Bentonit Dengan Bantuan Gelombang Mikro Serta Uji Fotodegradasi Terhadap Methylene Blue

SUMMARY
ZnO semiconductor is a metal oxide which has applications in the field of photodegradation. Some of the advantages of ZnO are small particle size, high exchange reaction activity and efficiency in the UV light region, however the ZnO catalyst has a large Band gap energy and is difficult to separate from water after the photocatalytic reaction limits its application in the treatment of water polluted with dyes. In this study, the ZnO/Bentonite composite was synthesized using microwave assistance which was used as a catalyst for the photodegradation test of methylene blue dye. XRD characterization showed that the crystal structure obtained had a hexagonal shape with a 10 gram ZnO/Bentonite composite crystal size of 18.85 nm. The results of UV-DRS characterization showed that there was a decrease in the band-gap energy from 3.21 eV on ZnO to 2.21 eV on 10 gram ZnO/Bentonite composite. The synthesis results were then tested for photodegradation of methylene blue and it was concluded that the ZnO/Bentonite composite could degrade 10 ppm methylene blue with optimum composite mass of 0.15 gram of 98.35 % within 140 minutes.
