Abstract

The reaction of TiCl4 with the surface of a silica gel has been investigated in detail using Fourier-transform IR photoacoustic spectroscopy (FTIR PAS) and elemental analysis. The hydroxy groups on the silica react with the TiCl4 giving rise to both monodentate and didentate surface groups. The parameters influencing the relative distribution of these groups have been studied. A quantitative description of the chemisorbed species has been obtained as a function of the pretreatment and the reaction temperatures.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
