New nitrides: from high pressure–high temperature synthesis to layered nanomaterials and energy applications

Abstract

We describe work carried out within our group to explore new transition metal and main group nitride phases synthesized using high pressure–high temperature techniques using X-ray diffraction and spectroscopy at synchrotron sources in the USA, UK and France to establish their structures and physical properties. Along with previously published data, we also highlight additional results that have not been presented elsewhere and that represent new areas for further exploration. We also describe new work being carried out to explore the properties of carbon nitride materials being developed for energy applications and the nature of few-layered carbon nitride nanomaterials with atomically ordered structures that form solutions in polar liquids via thermodynamically driven exfoliation. This article is part of the theme issue ‘Fifty years of synchrotron science: achievements and opportunities’.
