A new kinetic model of kaolinite dehydroxylation is proposed in order to take into account data obtained by gravimetry at 450 °C under controlled water vapour pressure ranging from 2.5 to 10 mbar. This model involves a process of random nucleation and anisotropic growth of nuclei. Under the above experimental conditions, the growth of nuclei on the surface of the particles is rapid, whereas the growth towards the inside of the particles is limited by two-dimensional diffusion. This model allowed us to evaluate the ‘areic frequency of nucleation’ and the ‘areic reactivity of growth’ for our experiments. The variation of the latter quantity with the water vapour pressure was also obtained by a method based upon a sudden pressure change during isothermal experiments. It is this variation which allows us to conclude that the growth of nuclei into the particle is limited, under our experimental conditions, by the diffusion of hydroxyl groups from the internal interface to the external one.

Physical Chemistry Chemical Physics

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.
