摘要

We investigated the hydrogenation of 3 and 10 nm Mg layers sandwiched between Ti using an optical transmission technique (hydrogenography). We observe in situ the two dimensional nucleation and growth of single hydride domains of up to several millimeters in diameter. The low density of nuclei points to preferential nucleation at heterogeneous sites. From an analysis of the growth kinetics we deduce an extremely large edge boundary energy, which we relate to the plastic deformations inherent to the 30% volume expansion of the MgH2. We find that the nucleation and growth process affects the hysteresis between absorption and desorption. Especially, the absorption branch can be lowered when nucleation barriers are removed. Our results show that when discussing the effect of nano-structuring on hydrogenation it may be quite complex to distinguish the thermodynamic and kinetic effects involved.

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.
