The structural and chemical stability of TiP2O7 has been investigated by Raman spectroscopy under an n-butane–O2–He gas mixture (1∶1∶2). Titanium pyrophosphate powders with low and high specific surface areas have been characterised up to 560 °C. No structural transition or chemical decomposition was evidenced under the gas feed used. However, the overall intensity of the Raman spectrum decreased sharply at 400 °C in parallel with the deposition of disordered graphite at the surface and reappeared above 450 °C when the carboneous compound burned. This phenomenon was completely reversible on decreasing the temperature. The deposit appearing with the reduction of TiP2O7 could arise from the trapping of reaction intermediates by oxygen vacancies at the surface. Above 450 °C, the carboneous compound disappeared when the diffusion rate of oxygen vacancies increased. The same phenomenon was observed on high surface area TiP2O7 for which supplementary bands assigned to surface modes were observed.

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.
