AlPO-18 nanocrystals synthesized under microwave irradiation

A novel solvothermal approach to synthesize SAPO molecular sieves using organic amines as the solvent and template

“…The XRD patterns of SAPO-18 were similar to those reported in the previous literatures. 37,38,40 The SEM images (Fig. 2) reveal that SAPO-34 had a typical rhombohedral morphology.…”

Kinetics of water adsorption in microporous aluminophosphate layers for regenerative heat exchangers

“…All the physicochemical parameters describing the AlPO-18 materials were presented earlier. [14] The dry layer mass of AlPO-18 layers were determined after heating of the samples to 120 °C for 1 h.…”

“…[14] The nanosized powders posses elongated hexagonal plate-like morphology. The monomodal particle size distribution shows an average particle diameter of 250 nm corresponding to the long axis of the nonspherical particles.…”

“…This is in a good agreement with the equilibrium sorption data of the corresponding powder samples. [14] In Figure 6 the water loading is normalized to the corresponding layer masses resulting in equilibrium loadings of 275 mg g -1 and 250 mg g -1 for "type N" and "type M" layers, respectively. The water capacities are exceptionally high for microporous molecular sieve materials, thus rendering AlPO-18 as a highly interesting compound for heat transformation and storage applications.…”

Optical properties of photopolymerisable nanocomposites containing zeolite nanoparticles

“…The zeolite nanoparticles differ in their chemical composition and structure, hydrophobic/hydrophilic nature and pore size [7]. The choice of large-pore size nanoparticles (BEA) [8] and medium to small-pore size nanoparticles (Si-MFI and AlPO-18) [9,10] allows us to distinguish between two situations -when the acrylamide monomer molecules can be trapped inside the nanoparticles (BEA) and when they are larger than the nanoparticles' pore size (Si-MFI, AlPO-18). AlPO-18 nanoparticles are known for their hydrophilic nature and their ability to retain water molecules inside their pores unless heated above given temperature [10] while Si-MFI nanoparticles are understood to remain empty due to their hydrophobic nature [9].…”
