Abstract

A facile methodology based on cyclic voltammetry is presented allowing the density of defects, viz edge plane like-sites/defects of carbon nanomaterials to be readily quantified. The approach is based on the construction of carbon nanomaterial paste electrodes which is measured using cyclic voltammetry and a standard electrochemical redox probe. This protocol allows a quantitative relationship between the heterogeneous electron-transfer rate and the density of defects to be readily determined and also provides researchers with a methodology to quantify the density of defects for comparative purposes.

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.
