Abstract

This work undertakes mechanistic studies of H+ reduction on a palladium microelectrode in a room temperature ionic liquid. It was found that the electrode was initially in a partially passivated state in [NTf2]− based RTILs and that pre-anodisation of the electrode surface has a dramatic effect on the reversibility of the system, also triggering a change from hydrogen evolution to hydrogen absorption. Theoretical modelling supported the idea of Pd/H formation under these conditions. Utilising Pd/H as an activated hydrogen source, a proof-of-concept method for hydrogenation of multiple bond containing organic molecules by in situ generation of Pd/H via reduction of H+ on palladium in a room temperature ionic liquid has been demonstrated.

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.
