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.

“…According to the discharge time (∆t, s), current density (I/m, A/g) and potential window (∆V, V), the specific capacitances (C, F/g) of GO/NA-Cl at 1, 2, 4, 6, 8, 10 and 20 A/g were calculated with the formula of C=(I× ∆t)/(m× ∆V) to be 1573, 1478, 1357, 1275, 1185, 1124 and 981 F/g, respectively (Figure 3(b)). [20] Therefore, the retention rate of the capacity is 81 % and 62 % at 6 and 20 A/g, respectively, indicating the charming rate capability of GO/NA-Cl electrode, which may be resulted from its large surface provide more electrochemical active site for redox reaction.

To meet the demands of modern vehicles and electronic devices, an increasing number of new materials for the cathode of high-performance supercapacitors have been studied in depth. Here, GO/NA-Cl composites were successfully fabricated by in-situ grow NiAl layered double hydroxide (NiAl LDH) nanosheets on graphene oxide (GO) flakes through one-step hydrothermal procedure for the cathode of supercapacitor. The image of scanning electron microscopy (SEM) exhibited that the NiAl-Cl LDH nanosheets were evenly and vertically arranged on the GO flakes and interlaced to form a network structure, presenting a considerable surface area, which afford abundant active sites in contact with the electrolyte and alleviate the expansion of GO/NA-Cl during the process of electrochemical reaction to improve its stability. The results of electrochemical test show that the GO/NA-Cl is a typical pseudocapacitive material, which provides a prominent specific capacity of 1573 F/g at 1 A/g, and superior rate property (the rate of capacity retention is 62% even at 20 A/g). Furthermore, the GO/NA-Cl electrode shows a superior cycling life after 1000 cycles at 1 A/g with about 80% capacitance retention.

“…Designing and regulating the interlayer spacing structure has become an essential topic in the research of LDH materials. Fruitful results have been achieved using experimental methods to modulate the interlayer spacing, such as changing the interlayer spacing and structural stability − by adjusting the anion size and type − and regulating the basal layer metal element ratio and synthesis conditions to improve functional properties. − NiAl-LDHs have many research reports on electricity storage, catalysis, adsorption, etc., and are expected to achieve industrial application. − The effects of anion intercalation of CO 3 2– , NO 3 – , Cl – , sodium dodecyl sulfate, etc., on the interlayer spacing of NiAl-LDHs have all shown that large interlayer spacing has a positive effect on supercapacitor and catalytic performances. However, the microscopic mechanisms affecting the layer spacing and stability of NiAl-LDHs were not systematically reported.…”

Interlayer spacing and structure stability of layered double hydroxides (LDHs) on their application performance in adsorption, ion exchange, catalysis, carrier, and energy storage is important. The effect of different interlayer anions on the interlayer spacing and structure stability of LDHs has been less studied, but it is of great significance. Therefore, based on density functional theory (DFT), the computational model with 10 kinds of anions intercalated Ni 3 Al-A-LDHs (A
