Abstract

Two Fe2O3–SiO2 nanocomposites containing 50% by weight of iron oxide were prepared by a sol–gel method. By changing the surface to volume ratio of the gelling mass from 0.04 (sample A) to 0.3 cm−1 (sample B), gelation times changed, resulting in nanoparticles of average size of about 10 and 4 nm, respectively. Accurate X-ray diffraction (XRD) data were collected and used to calculate total structure and correlation functions. The analysis of these functions unequivocally proved that in both samples maghemite is the iron oxide formed. The result demonstrated that decreasing the gelation time gives rise to the formation of smaller and smaller nanoparticles of the same phase. The possibility of interpreting the XRD pattern of sample B in terms of occurrence of 2-line ferrihydrite was discussed.

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.
