In the current study, an inexpensive solid-state mechanochemical technique is proposed for the in situ synthesis of nanostructured aluminum nitride (AlN) and carbon nanotubes (CNTs). The CNTs and nitrogen-doped CNTs are synthesized through a novel bottom-up milling approach in which melamine as the solid source of both carbon and nitrogen is milled with aluminum. However, the efficiency of CNT formation remarkably enhances when the milled powder is exposed to a subsequent heat treatment. The effect of various parameters such as milling media, aluminum-to-melamine molar ratio (Al/M), milling time and subsequent heating temperature on the yield and formation mechanism of the produced CNTs are assessed. A detailed characterization of the final products reveals that small amorphous carbon nitride domains resulting from polymerization of melamine molecules at the intermediate stages of milling are responsible for the synthesis of CNTs either during the milling or subsequent heat treatment processes.

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.
