The Effect of Surface Hydroxylation on MOF Formation on ALD Metal Oxides: MOF-525 on TiO2/Polypropylene for Catalytic Hydrolysis of Chemical Warfare Agent Simulants

“…A signal at 1125 cm −1 due to C−O stretching further points to TCPP bonding with Al−OH groups. After ZrOCl 2 solution, a new peak at 1660 cm −1 indicates water, 56 likely associated with adsorbed ZrOCl 2 •xH 2 O. This is evidence that the film hydroxylation treatment, which enabled expansion of the film and increased hydroxyl concentration, improved reactivity under these conditions.…”

Manifestations of Weak O–H···F Hydrogen Bonding in M(H2O)n(B12F12) Salt Hydrates: Unusually Sharp Fourier Transform Infrared ν(OH) Bands and Latent Porosity (M = Mg–Ba, Co, Ni, Zn)

“…Table S11 lists M–OH 2 and O­(H)···X distances (X = F, O, N) for the four M­(H 2 O) 6 (Z) structures and the structures of other relevant hexahydrate salts of Mg, Co, Ni, and Zn, including Mg­(H 2 O) 6 ­(B 12 H 12 ), Mg­(H 2 O) 6 ­(B 12 H 12 )­·6H 2 O, Mg­(H 2 O) 6 ­(SiF 6 ), Mg­(H 2 O) 6 ­(B 10 H 10 )­·4H 2 O, Mg­(H 2 O) 6 ­(B­(CN) 4 ) 2 , Mg­(H 2 O) 6 (SO 4 ), Mg­(H 2 O) 6 ­(UO 2 (EtCO 2 ) 3 ) 2 , Mg­(H 2 O) 6 (SO 3 ), (NH 2 Me 2 ) 2 Co­(H 2 O) 6 ­(SO 4 ) 2 ­·2H 2 O, Cs 2 (Co­(H 2 O) 6 ) 3 ­(HPO 3 ) 4 , Ni­(H 2 O) 6 ­(B 12 H 12 )­·6H 2 O, Ni­(H 2 O) 6 ­(VOF 4 ­(H 2 O)), Ni­(H 2 O) 6 ­(TiF 6 ), K 2 Zn­(H 2 O) 6 ­(SO 4 ) 2 , Zn­(H 2 O) 6 ­(B 12 H 12 )­·6H 2 O, and [Zn­(H 2 O) 6 ] 2 ­(ZrF 8 ) . It is clear that the ranges of, and average, M–OH 2 distances and the ranges of O­(H)···X distances do not depend on the size of, or the charge on, the counteranion.…”

“…The dehydration/rehydration behavior of M­(H 2 O) n (Z) salts is especially important in light of the interest in thermodynamic and kinetic dehydration/rehydration studies of salt hydrates for the storage of low potential heat from solar energy. − Some salt hydrates are known to change their structure when D 2 O replaces H 2 O . Many have been studied because they exhibit interesting phase-transition behavior and observable reorientational molecular motions of both cations and anions. − …”
