Sintesis Komposit Tio2/Zeolit Lta (Lynde Type-A) Sebagai Fotokatalis Untuk Degradasi Metilen Biru

---

Zeolite is an alumina silicate mineral that is effective as ion exchange. Synthetic zeolite has higher purity than natural zeolite and its adsorption activity is better. TiO2 semiconductor has a low absorption capacity that only occurs on the surface of the catalyst, so a support is needed to be able to to perform methylene blue degradation as well as possible. Zeolite is used as a support in the synthesis of TiO2/zeolite composites to increase the activity of TiO2 in the degradation of methylene blue. The resulting zeolite synthesis is a type of zeolite LTA in accordance with JCPDS data No. 39-222 and reinforced by the results of data software Crystal Impact Match! 3 Version 3.11.5.200. The synthesis of TiO2/zeolite LTA composite was carried out by impregnation method and the synthesis of zeolite was carried out by hydrothermal alkali fusion method. Composite synthesis was carried out with a mass ratio of TiO2:zeolite of (0.5:3; 1:3 and 1.5:3) g. The results of XRD data obtained crystal size with calculations from Debye-Schrerrer of 187.544 nm, 267.111 nm and 267.495 nm for each of the composite comparisons. TiO2/zeolite composites from FTIR data show the presence of O-H groups, O-Si-O groups, Ti-O groups, Al-O groups and the presence of double rings. The results of UV-DRS data obtained TiO2 band gap value of 3.15 eV and composite band gap values of 2.82 eV, 2.45 eV and 2.39 eV with methylene blue degradation results occurred by 60 %, 62.23 % and 71.05 % in each composite comparison. The best degradation results were obtained at the lowest absorbance value using the UV-Vis device, which is in the 1.5:3 g TiO2/zeolite composite with a methylene blue concentration of 10 ppm and the optimum degradation time at 210 minutes, 150 mg composite mass for 5 hours an equilibrium time of 65 minutes.
