Novel synthesis of rutile titanium dioxide–polypyrrole nano composites and their application in hydrogen generation

Abstract

This work presents the first report of rutile titanium dioxide (TiO2)–polypyrrole (PPy) nanocomposites prepared by chemical polymerization of pyrrole in situ in the presence of pure rutile phase TiO2 nanoparticles. The TiO2 rutile nanoparticles were made in water while the composite was made in a biphasic ionic liquid–water system. We attempted for the first time to split water under sunlight with this recoverable photocatalyst.
