“…The molecular density of the adsorbed MO on the LDH-S was estimated to be larger than 40 molecules nm −2 from SBET. Taking into account the two aspects, it is strongly suggested that the MO molecules existed in aggregates (Grégoire et al, 2019) or they were intercalated into the interlayer space (Neumann et al, 2002).…”

Systematic utilization of carbonated Mg-Al layered double hydroxide (LDH) nanosheets on methyl orange removal was investigated with a respect to particle dimension. LDHs with smallest dimension were synthesized carefully to have a small lateral size as well as high dispersibility. The other particles with medium and large sizes were prepared by hydrothermal treatment and urea hydrolysis to have larger size and higher crystallinity. According to kinetics and isotherm analyses, the smallest sized LDH showed effective adsorption of methyl orange (1250 mg/g-LDH) which was remarkable higher than the other LDHs with the larger lateral sizes. Compared with the larger lateral sized LDHs, the small sized ones were verified to utilize all the accessible adsorption sites of the nanosheets generating nanoconfinement of the methyl orange molecules. Transmission electron microscopy (TEM) and powder X-ray diffraction (PXRD) patterns definitely indicated that the LDHs with ~40 nm of the lateral dimension could fully utilize the interlayer nanospace of the LDH. Monte-Carlo simulation suggested the intercalated methyl orange could be stabilized not only through electrostatic interaction with the LDH layer but also by π-π stacking between the methyl orange molecules, which is thought to be the driving force to replace carbonate anion.

“…Ni1ZnO has more structural distortion than Ni3ZnO. The bond distance between the atom in positions The geometry optimization results of ionized MB and MO dyes do not show any significant difference from the experimental data [37][38][39], as shown in table 3. The calculated infrared spectrum of both molecules as displayed in figure 3 also in agreement with several literatures [40][41][42][43].…”

In this research, the adsorption of methylene blue (MB) and methyl orange (MO) on ZnO and nickel-doped ZnO (Ni-ZnO) clusters was investigated through the density functional theory (DFT). The study included the interaction with ionized MB, neutral MB, ionized MO and neutral MO. In the case of Ni-doped ZnO, the two probabilities of nickel multiplicities (1 and 3) have been included in the investigation. The interaction between water and ZnO cluster as well as water with Ni-ZnO multiplicity 1 and multiplicity 3 was also studied. The results showed that nickel doping can decrease the bandgap 25.38% which is promising to shift the UV source to the visible range in the photocatalytic process. For photocatalyst application it will bring the more benefit because it requires the lower energy. Moreover, the nickel doped induce the dye adsorp stronger when the dye attached to dircetly the zinc ion. This guide to design the N-doped ZnO photocatalyst with no nickel atoms on the surface of the photocatalyst.

“…To evaluate the possible interaction mechanisms between the [BMIM][PF 6 ]/MIL-53(Al) composite, and MB and MO dyes (Hasan and Jhung, 2015 ; Yoo et al, 2021 ), IR spectra of the composite before and after dye adsorption were investigated. Supplementary Figure 4 shows that after the adsorption, the characteristic peaks of the dyes (Somani et al, 2003 ; Raj et al, 2007 , Yu and Chuang, 2007 ; Grumelli et al, 2010 ; Shen et al, 2015 ; Ovchinnikov et al, 2016 ; Grégoire et al, 2019 ), ν(C–N), ν(C-S + ), and δ(C–H) for MB and ν(C–H), ν(S-O), and ν(C–N) for MO are present in the IR spectra of dye adsorbed on the [BMIM][PF 6 ]/MIL-53(Al) composite for single-component dye case. And as expected, the IR spectrum of [BMIM][PF 6 ]/MIL-53(Al) composite measured after the adsorption of the dye mixture has the characteristic peaks of both MB and MO.…”

We incorporated a water-stable ionic liquid (IL), 1-butyl-3-methylimidazolium hexafluorophosphate, [BMIM][PF6], into a water-stable metal–organic framework (MOF), MIL-53(Al), to generate the [BMIM][PF6]/MIL-53(Al) composite. This composite was examined for water purification by studying its capacity for methylene blue (MB) and methyl orange (MO) removal from aqueous solutions having either single dye or a mixture of both. Data illustrated that the removal efficiency and the maximum adsorption capacity of MIL-53(Al) were increased several times upon [BMIM][PF6] incorporation. For instance, within 1 min, 10 mg of pristine MIL-53(Al) adsorbed 23.3% MB from 10 mg/L of MB solution, while [BMIM][PF6]/MIL-53(Al) composite was adsorbed 82.3% MB in an identical solution. In the case of MO, 10 mg of pristine MIL-53(Al) achieved 27.8 and 53.6% MO removal from 10 mg/L of MO solution, while [BMIM][PF6]/MIL-53(Al) composite removed 61.4 and 99.2% within 5 min and 3 h, respectively. Moreover, upon [BMIM][PF6] incorporation, the maximum MB and MO adsorption capacities of the pristine MOF were increased from 84.5 to 44 mg/g to 204.9 to 60 mg/g, respectively. The adsorption of dyes in pristine MIL-53(Al) and [BMIM][PF6]/MIL-53(Al) followed a pseudo-second-order kinetic model and a Langmuir isotherm model. In a mixture of both dyes, the IL/MOF composite showed a doubled MB selectivity after the IL incorporation. The composite was successfully regenerated at least two times after its use in water purification to remove MB, MO, and their mixtures. Infrared (IR) spectra indicated that the MB/MO adsorption occurs on [BMIM][PF6]/MIL-53(Al) by electrostatic interactions, hydrogen bonding, and π-π interactions. These results showed that [BMIM][PF6]/MIL-53(Al) composite is a highly promising material for efficient water purification.
