Understanding surface (un)reactive sites of titania supports towards propyl-phosphonic acid surface modification Universiteit Antwerpen
Organophosphonic acids (PAs) surface modification on metal oxides is important for applications, nevertheless, a detailed study evaluating the influence of metal oxides surface properties on PAs modification is lacking. This work presents a method to qualitatively probe surface (un)reactive sites of titania towards propyl-phosphonic acid (3PA) grafting by methanol. It identifies the more or less reactive sites, i.e., hydroxyl groups and Lewis ...
