Abstract

Graphene-like BN nanosheets were synthesized via carbon-substitution reaction using graphene as a template in an attempt to produce C-doped BN. The carbon residue was removed by high-temperature oxidation in air. The role of the graphene template and oxygen with regard to the local structure of BN and its defect-related optical luminescence are investigated using X-ray absorption near-edge structure (XANES) and X-ray excited optical luminescence (XEOL). The structure and bonding of B, N, C and O in different chemical environments before and after oxidation are revealed by XANES. It is found that B and N atoms tend to form large BN domains, whereas the formation of B–C or N–C bonding is not significant. Two types of O local structures are found under different oxidation temperatures, as revealed by XANES: moderate oxidation results in O substituting N, while B2O3-like local structure is formed under higher oxidation temperature. The two types of O-related defects exhibit different luminescence properties.

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.
