Mesoporous titanium nitride supported Pt nanoparticles as high performance catalysts for methanol electrooxidation
Literature Information
Minghui Yang, Zhiming Cui, Francis J. DiSalvo
Mesoporous titanium nitride (TiN) with high surface area and good electrical conductivity was prepared by a novel solid–solid phase separation method from a Zn containing titanium oxide, Zn2TiO4. The PXRD shows single phase rocksalt structure of TiN with a domain size of 25 nm. The conductivity of mesoporous TiN at 35 bar is 395 S cm−1. The Pt/TiN catalyst exhibits more negative onset potential for methanol electrooxidation (0.15 V) than Pt/C (0.22 V), showing a higher intrinsic electrocatalytic activity, while its peak current density (228 mA mg−1 Pt) is ∼1.5 times higher than that of Pt/C (148 mA mg−1 Pt). The Pt/TiN catalyst also demonstrates excellent long-term stability. This work provides an efficient method to prepare mesoporous nitrides as a promising support towards oxidation of small organic molecules in fuel cells.

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.
