Magic angle spinning NMR investigations on amorphous aluminophosphate oxynitrides
Literature Information
Multinuclear magic angle spinning NMR spectroscopy has been applied to characterise the nitrogen species present in aluminophosphate oxynitrides, i.e. AlPONs, prepared by ammonolysis of high surface area aluminophosphates. At room temperature, the NH3 enters the coordination sphere of some tetrahedral Al in the amorphous AlPO4 to increase its coordination to 5 and 6. The IR spectra show bands characteristic of NH3 and NH4+, while the 31P spectrum gives a new low field component that reflects the influence of adsorbed NH3 and/or NH4+. When the aluminophosphate precursor is treated with ammonia at temperatures within the interval 1073–1123 K, a deeper modification of the AlPO4 occurs giving rise to new nitrogen species, which remain after outgassing above room temperature, and are tentatively assigned to –P–NH2 terminal groups. When the ammonolysis is carried out at 1273 K an aluminophosphate trydimite phase appears, and nitrogen must be engaged in the formation of moieties of the type PO4-xNx, with x>1.

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.
