Computer simulation study of filling pores of mesoporous silica with magnetic iron oxide nanoparticles which are diffusing towards the silica surface from a water solution with a given pH was presented. Three different values of the pH of the solution were under consideration, pH = 4, 7, and 10. The size of nanoparticles was of the order of magnitude of the nanopore diameter. It was observed that...
In 1965 Parks compiled PZC of metal oxides and hydroxides and his paper is still the most frequently cited source of PZC of these materials. The recent compilation (Kosmulski 2001) covers not only oxides and hydroxides, but also mixed oxides, sparingly soluble salts and other materials whose surface charging is pH dependent. One set of data from this compilation (155 PZC of AL2O3 published in 150...
