Abstract

Proton transfer processes from mineral acids to bases (HX, where X = F, Cl, Br and I to ammonia) are normally feasible in solution and they cannot spontaneously occur in the gas phase. We demonstrate that this process can be feasible under nanoconfinement without using any solvent molecules. More interestingly, in contrast to the general observation, halide ions except fluoride behave like protons under high confinement, leading to the formation of NH3X instead of NH4 ions. The triggering transformation of hydrogen bonded to the proton transferred complex under nanoconfinement is explained based on the thermodynamic quantity, static pressure.

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.
