Synthesis, Characterization, and Photocatalytic Activity of N-Doped TiO2/Zeolite-NaY for Methylene Blue Removal

Dye is an important compound in textile industry. The famous dye for coloring of textile is methylene blue. Methylene blue degradation has been difficult when carried out naturally by microorganisms. The advanced oxidative process is a promising method to degrade methylene blue using semiconductor material TiO2 and its modification. The modification catalyst of TiO2 such as TiO2-N, TiO2/zeolite-NaY and TiO2-N/zeolite-NaY. These materials were synthesized by mixing TiO2 and urea, then followed by impregnation of the mixture to zeolite-NaY as support material. The materials have been synthesized then characterized by XRD, and FTIR. Degradation of methylene blue on the synthesized materials was tested under UV light for 5, 20, 30, 40, and 50 minutes. The results showed that the diffractogram of TiO-N/zeolite-NaY and TiO2/zeolite-Y has a similar spesific peak with TiO2 and zeolite-NaY. It indicates that the impregnation process was sucessfully. TiO2/zeolite-NaY and TiO2-N/zeolite-NaY also showed the excellent activity for degrading methylene blue, which reached up to 99% for 3 hours of reaction.

Methylene blue is the most widely used dye in the industry and it is difficult to be degraded by the microorganism. This research aims to investigate the photocatalytic activity and effects of contact time on the photocatalytic degradation rate of methylene blue by TiO2/Zeolite-NaY and TiO2-N/Zeolite-NaY material based on the kinetic study. The Advanced Oxidative Process (AOP) method was used to degrade methylene blue. Furthermore, the AOP is a degradation process that uses semiconductor material such as TiO2 or modification catalyst of TiO2 to be TiO2/Zeolite-NaY and TiO2-N/Zeolite-NaY. The degradation of methylene blue with catalyst TiO2/Zeolite-NaY and TiO2-N/Zeolite-NaY were tested under UV light for 5, 20, 30, 40, and 50 minutes. The result showed that TiO2/Zeolite-NaY and TiO2-N/Zeolite-NaY had an excellent activity for degrading the dye, which reached up to 99% after 20 and 30 minutes reaction, respectively. Also, a kinetic study of methylene blue degradation on TiO2/Zeolite-NaY and TiO2-N/Zeolite-NaY showed the kinetic models were according to pseudo-second-order.

A facile route was demonstrated to obtain an efficient graphene-hybridized TiO2 photocatalyst. The photodegradation results of Methylene Blue over graphene hybridized with TiO2 showed that the photocatalytic activity could be significantly enhanced under UV light irradiation. The structure between TiO2 and graphene as well as its effect on the photocatalytic activity were systematically investigated. The mechanism of the enhanced photocatalytic activity is based to the high migration efficiency and the inhibition of recombination of photoinduced electron-hole pairs. The graphene hydridization is proven to be a promising approach to develop highly efficient and stable photocatalysts under UV light irradiation.

The progress of the textile industry can increase the amount of dyestuff waste, but often waste disposal is overlooked. The purpose of this research is to provide solution in handling river water pollution by textile industry dye waste. The degradation of textile industry dye waste can be done with TiO2 semiconductors with UV light as a source of irradiation, but only 5% of sunlight can be utilized TiO2 to excite its electrons, so degradation process is not effective. It needs a material that can optimize the activity of TiO2 semiconductor, one of them C-dot coming from cassava skin. The results obtained in this research were TiO2/C-dot composite which could degrade methylene blue where its effectiveness was tested using UV-Vis spectrophotometer instrument. TiO2/C-dot photocatalyst activity test for methylene blue 0.0001 M showed that the concentration of 20% with the amount of degradation up to 96,99%, best type of rays was sunshine with amount of degradation up to 66,25% and longest radiation in sunshine with the amount of degradation was up to 78.77% and UV with the amount of degradation up to 75.99%.

Economic Standpoint

The textile industry including batik has provided broad benefits to society from an economic standpoint. However, there is negative impact from wastewater generated in the production process, which is containing dyes. Various types of dyes are used in the coloring process, and methylene blue is one of most used dye. Various ways have been done to treat wastewater containing methylene blue. Methylene blue processing techniques by adsorption have been carried out with various types of adsorbents. Research on the comparison of the ability of commercial activated charcoal and commercial activated zeolite to adsorb methylene blue was carried out with the addition of an Fe catalyst and a hydrogen peroxide oxidizer. The results showed that the addition of Fe catalyst would increase the degradation of methylene blue in the waste either with activated charcoal or activated zeolite. The combination of using Fe catalyst and hydrogen peroxide oxidizer further increases the removal of methylene blue in both types of adsorbents, activated charcoal and activated zeolite. Activated zeolite has the better ability to adsorb methylene blue than activated charcoal under various conditions.

Methylene Blue Degradation

TiO2 is one of the most attractive metal oxides because of the excellent chemical and photocatalytic properties. However, a problem in the application of TiO2 is the large band gap energy of 3.2 eV, corresponding to its photocatalytic activity under UV-light irradiation of wavelengths <387 nm. In this work, TiO2 nanoparticles doped with iron were grown on the surface of functionalized carbon nanotubes (TiO2-Fe@CNTs) to expand the photoabsorbance of the nanocomposite materials in the visible light region and improve their photocatalytic activity. TiO2-Fe@CNTs nanocomposite materials were synthesized by hydrothermal route in Teflon-sealed autoclave at 180oC for 10h. The FE-SEM and X-Ray diffraction measurements were taken for morphology and structural analysis of TiO2 nanoparticles doped with Fe coating on CNTs. The effects of the iron and CNTs on the enhanced photocatalytic activity for methylene blue degradation under AM 1.5 illumination of 100 mW.cm−2 were investigated.

THE EFFECT OF ADSORBENT TYPE AND RATIO ON REMOVAL AND ISOTHERM ADSORPTION OF METHYLENE BLUE. Methylene Blue (MB) is one of the dye that are widely used in the textile industry. The wastewater from textile industry that contain MB can reduce the oxygen level in water bodies. This study aims to determine the efficiency of the adsorbent in MB removal and to analyze the isotherm adsorption. The variations conducted in this research was the type of adsorbent and its ratio. The activated carbon that used as adsorbent was fresh betel nut (Cyrtostachys lakka) activated carbon (A), regenerated betel nut activated carbon (B), and coconut shell activated carbon (Cocos nucifera) (C). The type of adsorbent was AB, AC, and BC with ratio of 1:1, 1:2, 1:3, 2:1, and 3:1. The MB concentration was analyzed by using UV-Vis spectrophotometer. Isotherm adsorption was calculated based on Freundlich and Langmuir. The best results showed that the combination of fresh and regenerated betel nuts (AB) with ratio of 3:1 can remove 97.77% of MB. The adsorption process of MB in aqueous solution followed the Langmuir model with regression over 0.99 and adsorption capacity in the range of 2.14 mg/g - 3.53 mg/g.

Abstract In this study removal of methylene blue (MB) from an aqueous solution by zeolite (NaY) and related modified hierarchical zeolite (MY) has been investigated. The NaY zeolite with a low ratio of Si/Al was synthesized from silica extracted rice husk ash. It was transformed to hierarchical zeolite (MY) by a “destructive-constructive” modification method using tetramethyl ammonium hydroxide (TMAOH) and a cationic surfactant (Cetyltrime-thylammonium bromide, CTAB) as a templating agent. Various characterization method like FT-IR, XRF, XRD, BET, TGA, SEM and BJH confirmed the construction of parent zeolite and also successfulness of the modification process. EDX showed a negligible change of Si/Al ratio during modification which is favorite in adsorption of cationic MB dye. In order to study the interaction between the surface of adsorbent and adsorbate, six common isotherms were used. By Langmuir isotherm, it is clarified that, the maximum adsorption capacity (qm) had improvement from 15.2 mg g-1 to 133.1 mg g-1 for NaY and MY, respectively. The kinetic studies showed that the adsorption obeys the Pseudo-second order model for both NaY and MY zeolites. Also, the usage frequency of the MY was investigated. Results showed that there was not any noticeable change in performance of adsorption after four circles.
