要旨

Porous one-dimensional Mo2C–amorphous carbon composites, fabricated by in situ solid state reactions, are exhibited as effective and high-performance electrocatalysts towards the hydrogen evolution reaction (HER). The morphological and structural characteristics of the Mo2C based electrocatalysts were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The analyses showed that they had various advantages for the HER, including a high crystallinity, porous and tubular characteristics and good conductivity. The porous one-dimensional Mo2C–amorphous carbon composites with a larger content of Mo2C and moderate thickness of the carbon layers exhibited superior catalytic activities for HER to most of the Mo2C based electrocatalysts recently reported.

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.
