Abstract

Enhancing catalytic selectivity of supported metal nanoparticles with capping ligands is demonstrated using an Au/SiO2 catalyst in liquid phase aerobic oxidation of benzyl alcohol. Chemisorption of an appropriate amount of polyvinylpyrrolidone on the Au/SiO2 catalyst greatly enhances the benzaldehyde selectivity from 43% to ∼100% and its yield from 4.9% to 7.2%.

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.
