Platinum loaded CeO2–ZrO2/SBA-15 composite material catalyzes CO oxidation at lower temperatures (<100 °C) than conventionally prepared Pt/CeO2–ZrO2 (>150 °C). A sequence of reduction and reoxidation of CeO2- and ZrO2-loaded samples promotes the formation of CeO2–ZrO2 solid solution on the siliceous surface as indicated by wide-angle X-ray diffraction (XRD) patterns. Furthermore, initial coating of ZrO2 on the silica walls is quite important before CeO2–ZrO2 loading in order to obtain the CeO2–ZrO2 solid solution. The presence of CeO2–ZrO2 particles inside the mesopores is confirmed by N2 adsorption, low-angle X-ray diffraction, and scanning transmission electron microscopy (STEM) images. The solid solution of CeO2–ZrO2 in the confined mesoporous space forms more Ce3+ centers associated with oxygen vacancies on the surface due to the smaller size of the dispersed particles and these Ce3+ centers are believed to be responsible for the higher catalytic activity.

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.
