In this paper, the structures of 500 nm thick Mg–Pd films were tailored by insertion of 1 nm thin Ti interlayers, and their electrochemical hydrogen storage properties were investigated. Results showed that thin Ti interlayers in the Mg bulk film could significantly improve the discharge properties of thick Mg–Pd films. The Mg100–Ti1 sample exhibited the most promising electrochemical properties, including a shorter activation period, larger discharge capacity, superior cyclic stability and high rate discharge capability, due to the creation of numerous interfaces and nucleation sites, reduction of the hydrogen diffusion path, and synergetic catalytic effects of Pd and Ti layers.

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.
