Two Hybrid

Under hydrothermal conditions, two copper phosphonates, [Cu2(H2O)2(H2L)(bpy)2(H3L)2]·2H2O (1) and [Cu2(H2O)2(H2L)2(phen)2]·6H2O (2) (H4L = p-xylylenediphosphonic acid, bpy = 2,2'-bipyridine and phen = 1,10-phenanthroline), have been synthesized using diethyl p-xylylenediphosphonate (dixdp), in which p-xylylenediphosphonic acid (H4L) was generated via in situ hydrolysis. Complexe 1 forms a zero-dimensional (0D) bimetallic rings, while complex 2 features a 0D structure containing two kinds of partially deprotonated H3L-and H2L2-ligand.

Naoh Solution

Silicalite-1 membranes were successfully synthesized on α-Al2O3 tubes by in-situ hydrothermal synthesis after filling the tubes with water and glycerol mixtures, and all the membranes show high concentration performance towards ethanol/water mixtures after pretreating tubes with different NaOH solution. The results show that the flux enhances with the enhancement of NaOH solution concentration, but the separation selectivity decreases with the enhancement of NaOH solution concentration. After pretreating the α-Al2O3 tubes with different NaOH solution, the weight of all the α-Al2O3 tube decreases, but the Si/Al ratio increases, which shows that suitable pretreatment of α-Al2O3 is useful for improving the hydrophobicity of silicalite-1 membranes.
