Ultrasonic synthesis of a 3D Ni(II) Metal–organic framework at ambient temperature and pressure: New precursor for synthesis of nickel(II) oxide nano-particles

Sonocrystallisation of ZIF-8 in water with high excess of ligand: Effects of frequency, power and sonication time

“…The main impact of US was on the crystal size, as observed previously for other systems in which US has been applied [9] , [11] , [12] , [14] , [15] , [16] , [17] , [18] , [19] , [21] , [22] , [61] , [62] . The effects of US and mixing seem to be analogous because similar crystal size reductions were detected.…”

“…In comparison to synthesis without US, the main effects of sonochemical synthesis of MOFs are: a quicker reaction, decrease in crystal size [11] , [12] , [13] , [14] , [15] and morphology transformation [16] , [17] . However, no clear effects have been detected on the purity [13] , [18] , [19] , [20] , while inconsistent results have been reported on effects on surface area and porosity [11] , [13] , [15] , [20] , [21] , [22] . These inconsistencies are certainly related to the variation among different MOFs: different structures, different bonds and different synthetic routes.…”

Design and synthesis of coordination polymers with chelated units and their application in nanomaterials science

“…Thermolysis imidazoledicarboxylic acid), at 700 C under air yielded NiO nanoparticles, which size and morphology depends on the particle size of the initial compound. 341 The crystalline and nano-structures of two Pb(II) CPs, [Pb 2 (L) 4 (MeOH)] n (L ¼ 2-pyrazinecarboxylic acid) and [Pb(L 0 ) 2 ] n (L 0 ¼ 2-quinolinecarboxylic acid), were thermolyzed to prepare PbO nanoparticles with various morphology and size. 254 It should be noted that N,S-containing ligands were used not only to prepare metal sulde nanoparticles, as expected, but also metal oxides, more thermodynamically stable in air.…”

High-throughput ultrasonic synthesis and in situ crystallisation investigation of metal phosphonocarboxylates

“…Ultrasonic synthesis has been mainly applied in the field of organic synthesis, 1 but it has also been used in the synthesis of inorganic 2 and inorganic-organic hybrid [3][4][5][6] compounds. Syntheses under ultrasonic conditions can be generally carried out under relatively mild reaction conditions while locally extreme conditions are present.…”

“…10 In the field of inorganic-organic hybrid compounds, the use of ultrasound has been employed mainly to synthesise nano-particular reaction products. 7,11 Thus metal caboxylates such as [Na 16 (Ni 8 L 12 )(H 2 O) 20 (H 3 O) 4 ]•CH 3 CN•18.5H 2 O (H 3 L = 4,5-imidazoledicarboxylic acid), 3 [Zn(H 2 O)(BDC)], 4 or MOF-5 ([Zn 4 (µ 4 -O)(BDC) 3 ]) (H 2 BDC = terephthalic acid) have been described. 5 A porous zinc imidazolate containing a photoswitchable ligand has also been recently reported.…”
