Layered double hydroxides (LDHs) have occupied an important place in the fields of catalysts, electrocatalysts, and fillers, and their applicability can be greatly enhanced by interlayer organic modifications. In contrast to general organic modification based on noncovalent modification using ionic organic species, this study has clarified in situ interlayer covalent modification of LDH nanoparticles (LDHNPs) with the tripodal ligand tris(hydroxymethyl)aminomethane (Tris-NH2). Interlayer-modified CoAl LDHNPs were obtained by a one-pot hydrothermal treatment of an aqueous solution containing metal salts and Tris-NH2 at 180°C for 24 h. Tris-NH2 was covalently bonded on the interlayer surface of LDHNPs. Interlayer-modified NiAl LDHNPs were also similarly synthesized. Some comparative experiments under different conditions indicate that the important parameters for interlayer modification are the number of bonding sites per a modifier, the electronegativity of a constituent divalent metal element, and the concentration of a modifier; this is because these parameters affect the hydrolytic stability of alkoxy-metal bonds between a modifier and a layer of LDHNPs. The synthesis of interlayer-modified MgAl LDHNPs was achieved by adjusting these parameters. This achievement will enable new potential applications because modification of only the outer surface has been achieved until now. Interlayer-modified LDHNPs possessing CO32- in the interlayer space were delaminated into monolayers under ultrasonication in water. The proposed method provides a rational approach for interlayer modification and facile delamination of LDHNPs. Layered double hydroxide nanoparticles (LDHNPs), whose interlayer surfaces were organically modified with tripodal ligands, were prepared, and they showed improved delamination behavior in water under ambient conditions. Factors affecting the interlayer modification of LDHNPs were discussed on the basis of the stability of alkoxy bonds between the LDH layers and the ligands. In addition to this study using 2-Aminopropane-1,3-diol, there are many other studies that have used 2-Aminopropane-1,3-diol(cas: 534-03-2Computed Properties of C3H9NO2) was used in this study.
2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime. Examples of direct uses of amines and their salts are as corrosion inhibitors in boilers and in lubricating oils (morpholine), as antioxidants for rubber and roofing asphalt (diarylamines), as stabilizers for cellulose nitrate explosives (diphenylamine), as protectants against damage from gamma radiation (diarylamines), as developers in photography (aromatic diamines), as flotation agents in mining, as anticling and waterproofing agents for textiles, as fabric softeners, in paper coating, and for solubilizing herbicides.Computed Properties of C3H9NO2
