Characteristics of interfacial water at nanosilica surface with adsorbed 1,3,5-trihydroxybenzene over wide temperature range

Abstract Interfacial water at a surface of nanosilica ( S BET  = 378 m 2 /g) with various amounts of adsorbed 1,3,5-trihydroxybenzene (phloroglucinol, PG), which as an ice-nucleator can strongly affect water structure, was studied using 1 H NMR method with layer-by-layer freezing-out of bulk and interfacial water at 200  T C PG ). The 1 H NMR spectra depict appearance of non-freezable water and amorphous ice ( T C PG value. These effects are reflected in the water characteristics not only at T C PG value. The ordering effect of PG on water substantially increases when the PG content is higher than the monolayer coverage and the PG molecules can form oligomers.
