Liquid–solid surface interactions in some heterogeneous systems based on nitrobenzene

Two types of heterogeneous systems containing nitrobenzene (NB) as a filler (the first one is based on mesoporous molecular sieves of the MCM-41 type and the second one includes TiO 2 particles of different crystalline modifications—anatase and rutile) have been investigated by means of IR spectroscopy. The interactions of NB molecules with the surface active centers have been studied. According to obtained results the suggestion has been made that the possible mechanisms of molecular interactions in these complex systems are a creation of hydrogen bonds of –NO⋯HO–Al(Si) and –NO⋯HO–Ti types correspondingly.
