Abstract

This communication shows experimental results that clearly demonstrated the influence of the crystalline surface structure of the platinum electrode on the early stages of the electropolymerization of pyrrole in aqueous media. The platinum surface structure determines adhesion, coverage level, charge transfer properties as well as bulk properties of the synthesized film like morphology and the ion exchange kinetics during its reduction and oxidation. It is proven that the Pt(110) an Pt(111) surfaces are more suitable for obtain polypyrrole films with higher conductivity and charge-storage capacity than the Pt(100) surface.

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.
