In the present study, composite layer double hydroxide-metal oxide (Ni/Al-TiO2 and Ni/Al-ZnO) was successfully prepared and used as catalyst of oxidative desulfurization of dibenzothiophene. Characterization of catalyst was used XRD, FTIR, and SEM-EDS. The structure of Ni/Al-LDH, TiO2, and ZnO in composite Ni/Al-TiO2 and Ni/Al-ZnO was consistent, which also indicated that the preparation of composite did not change the form of precursors. FTIR spectra of Ni/Al-TiO2 and Ni/Al-ZnO absorption band at 3398, 1639, 1339, 832, 731, and 682 cm−1. The catalysts have an irregular structure, TiO2 and ZnO adhere to the surface of Ni/Al LDH. The percent mass of Ti and Zn on the composite at 29.3% and 18.2%, respectively. The acidity of Ni/Al LDH increased after being composited with TiO2 and ZnO. The optimum reaction time, dosage catalyst, and temperature were 30 min, 0.25 g, and 50°C, respectively, and n-hexane as a solvent. The percentage conversion of dibenzothiophene on Ni/Al-LDH, TiO2, ZnO, Ni/Al-TiO2, and Ni/Al-ZnO were 99.44%, 91.92%, 95.36%, 99.88%, and 99.90%, respectively. The catalysts are heterogeneous system and the advantage is that can be used for reusability. After 3 times catalytic reactions, the conversion of dibenzothiophene still retains more than 80%, even Ni/Al-TiO2 and Ni/Al-ZnO composites still 97.79% and 98.99%, respectively.

NiAl-LDH and ZnAl-LDH intercalated polyoxometalate K4 [SiW12O40] and K3 [PW12O40] were synthesized to form composite NiAl-[SiW12O40], NiAl-[PW12O40], ZnAl-[SiW12O40], and ZnAl-[PW12O40]. The physicochemical properties of the materials were characterized by XRD, FTIR, SEM, and UV-DRS. The material used for degraded Rhodamine B (RhB) as a cation dye. The results successfully synthesized by showed the peak diffractions angles at 11.63°, 23.13°, and 35.16° for NiAl-LDH and diffractions at 10.39°, 20.17°, 34.6° and 60.52°for ZnAl-LDH. The LDH typical structure of the composite materials NiAl-[SiW12O40] and NiAl-[PW12O40] was demonstrated by apparent diffraction at 2???? angles of 10.76°, 26.59°, 30.8°, and 63.11° for NiAl [PW12O40], 2???? angles at 8.26°, 11.34°, 29°, and 35.1° for NiAl-[SiW12O40], 7.73°, 28.6° and 35.6° for ZnAl-[PW12O40], and 8.61°, 25.27°, 34.96° and 66.34° for ZnAl-[SiW12O40]. The materials were characterized as an advanced catalyst to improve photocatalytic activity for RhB elimination under visible light sources. The intercalation of polyoxometalate [SiW12O40]4- and [PW12O40]3- into LDH could enhance the degradation cationic dye of RhB. Intercalation improved the photodegradation performance determined under UV-Vis irradiation conditions which composite NiAl-LDH was better than ZnAl-LDH composite. It was present by the %degradation RhB performances NiAl-LDH, ZnAl-LDH, NiAl-[SiW12O40], NiAl-[PW12O40], ZnAl-[SiW12O40], and ZnAl-[PW12O40] were 91.48%, 88.59%, and 88.41%, and 87.87%, respectively. The %degradation for NiAl-LDH and ZnAl-LDH was 68.94% and 65.76%. Recovery and reusability experiment of the catalyst demonstrated by degradation percentage that the LDH intercalated polyoxometalate has a great photocatalytic ability.

In this study, the Zn/Al-TiO2 and Zn/Al-ZnO was successfully synthesized. The catalysts were characterized by X-ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), and Scanning Electron Microscope—Energy Dispersive X-ray Spectroscopy (SEM-EDS). The typical diffraction peaks of Zn/Al-LDH, TiO2, and ZnO still appear in the Zn/Al-TiO2 and Zn/Al-ZnO composites, indicating that the composite preparation did not change the form of precursors. FTIR spectra of Zn/Al-TiO2 and Zn/Al-ZnO showed absorption band at 3448, 1627, 1381, 832, 779, and 686 cm-1.
