“…At the same time, it can be found that the morphology of NH 2 -MIL-125(Ti) changed from a cubic structure to a dish-like shape during the synthesis of the composite photocatalyst. It may be due to the change of pH or pressure during the preparation of the composite catalysts, which was consistent with the conversion conditions between different morphologies of NH 2 -MIL-125(Ti) reported in previous literature [27,28]. Nevertheless, it can be seen from the results of XRD and XPS that the introduction of BiOI did not affect the crystal structure of NH 2 -MIL-125(Ti).…”

The BiOI/NH2-MIL-125(Ti) composite photocatalyst with excellent photocatalytic performance was prepared by the solvothermal method. For the BiOI/NH2-MIL-125(Ti) (BNMT) system, the contents of NH2-MIL-125(Ti) in BNMT-4, BNMT-5, BNMT-7, BNMT-9, and BNMT-10 were 4 wt %, 5 wt %, 7 wt %, 9 wt %, and 10 wt %, respectively. XRD, XPS, SEM, and TEM characterizations indicated that BiOI/NH2-MIL-125(Ti) was successfully prepared. Brunauer, Emmett, and Teller (BET) and UV–vis diffuse reflectance spectra photoelectrochemical analysis indicated that BNMT-9 can make the specific surface area and photo absorption region larger than BiOI. In addition, the separation efficiency of photogenerated carriers was improved, and the recombination efficiency was reduced. The degradation percentages of Rhodamine B (RhB) and p-chlorophenol (P-CP) reached 99% and 90% over BNMT-9 under visible light irradiation. Additionally, the catalysts had high stability. The results of the active spices trapping experiments test indicated that h+ was the main active species. The possible degradation mechanism was proposed.

“…2B shows the FT-IR spectra of NH 2 -MIL-125. These spectra exhibit typical vibrational bands in the region of 1345–1610 cm −1 for the carboxylic acid functional group of the Ti-coordinated MOF structure, as well as O–Ti–O vibration over the range 400–800 cm −1 , 25 with no differences observed for the three samples.…”

“…In our work, the concentration of the reactant was the same when adding different kind of alkali metal salts, but the total ion concentration was decreased in the sequence of Li, Na, and K, which caused the different growth rates. Hu et al reported that the perfect NH 2 –MIL125 crystal should be rhombic dodecahedron morphology by Bravais-Friedel-Donnay-Harker (BFDH) theory [30]. It can be concluded that these morphology changes were affected by the total concentration of the ions in the solvothermal precursors.…”

Effects of Alkali Metal (Li, Na, and K) Incorporation in NH2–MIL125(Ti) on the Performance of CO2 Adsorption

A series of titanium-based, metal–organic framework (MOF) materials, xM@NH2-MIL125(Ti) (x is the alkali metal loading percentage during the synthesis; M = Li, Na, K), have been synthesized solvothermally. Alkali metal doping in the NH2–MIL125(Ti) in situ solvothermal process demonstrated a vital modification of the material structure and surface morphology for the CO2 adsorption capacity at ambient conditions. By changing the reactants’ precursor, including different kinds of alkali metal, the morphology of xM@NH2–MIL125(Ti) can be adjusted from a tetragonal plate through a circular plate to a truncated octahedron. The variation of the alkali metal loading results in substantial differences in the CO2 adsorption. The properties of xM@NH2–MIL125(Ti) were evaluated via functional group coordination using FT-IR, phase identification based on X-ray diffraction (XRD), surface morphology through scanning electron microscopy (SEM), as well as N2 and CO2 adsorption by physical gas adsorption analysis. This work reveals a new pathway to the modification of MOF materials for high-efficiency CO2 adsorption.
