Abstract

A preparation method for catalyst layers of platinum nanoparticles, as used in direct methanol fuel cells, based on pulsed electrochemical deposition within the three-phase boundary regions responsible for electrochemical reactions, was developed. A platinum precursor was brought into a carbon–Nafion layer and platinum was deposited in situ on the carbon surface. The size, size distribution and crystallinity of the deposited catalyst particles were determined by means of high-resolution transmission electron microscopy and X-ray diffraction measurements. The electrochemically active surface area of the deposited catalyst material was investigated by cyclic voltammetry, analysing the Pt–H oxidation peak.

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.
