Solvothermal and Ionothermal Approaches to Carbon Nitride Chemistry

Abstract

This thesis deals with investigations on the high-temperature treatment of carbon nitride precursors in various inorganic solvents. Particular attention was paid to the exploratory development of successful synthesis routes for the preparation of new graphite-like carbon nitride materials with improved crystallinity. Different molecular and polymeric s-triazinebased compounds have been synthesized by ammonothermal and hydrothermal treatment as well as by the utilization of salt melts. Furthermore, physical properties such as the bandgap and photocatalytical activity towards water splitting have been examined for individual compounds.
