The hydrogenation of crotonaldehyde over Cu/Al2O3 which was modified by formic acid or acetic acid adsorption has been investigated, exposed Cu sites being characterised using infrared spectroscopy with CO as a probe molecule. Formic acid adsorption on reduced Cu0 sites generated adsorbed bidentate formate which blocked CO adsorption at many sites, induced cationic character at the remaining available sites, and partially poisoned hydrogenation reactions. Modification of the surface poisoned CO hydrogenation more than CC hydrogenation and hence promoted butanal as the dominant hydrogenation product. Desorption of formate by “ flashing” at high temperature resulted in a partly reconstructed surface which gave higher catalytic activities than an unmodified surface before formic acid treatment. However, crotyl alcohol remained a minor product. The effects of acetic acid adsorption were similar to those for formic acid except that attempts at desorption of the modifier resulted in carbonaceous residues which partially poisoned both CO adsorption and 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.
