Incorporation of Pd into Au(111): enhanced electrocatalytic activity for the hydrogen evolution reaction
Literature Information
Peter J. Schäfer, Ludwig A. Kibler
While monolayer formation by under potential deposition of palladium from 0.1 M H2SO4 + 0.2 mM PdSO4 onto Au(111) commences around 0.6 V vs. SCE (saturated calomel electrode), there is evidence for slow incorporation of Pd0 into Au(111) under the same experimental conditions at 0.8 V, already. The presence of chloride traces suppresses such incorporation by forming stable complexes like [PdCl4]2−, which are strongly adsorbed on the surface. Less than 1% of a Pd monolayer are incorporated after immersion of Au(111) at 0.8 V into 0.1 M H2SO4 + 0.2 mM PdSO4 for 30 minutes. It is supposed that incorporated Pd preferentially occupies subsurface sites near Au steps, which is supported by theoretical calculations. Despite the low Pd coverage, the electrocatalytic activity for the hydrogen evolution reaction (HER) in 0.1 M H2SO4 is enormously high. The immersion time is crucial for the HER electrocatalytic 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.
