A simple approach to synthesize g-C<inf>3</inf>N<inf>4</inf> with high visible light photoactivity for hydrogen production

Abstract:

Se-modified g-C3N4 was synthesized from sonicated aqueous suspensions of melamine cyanurate and SeO2. The different thermal condensation temperatures in the 500-650 °C range were found to influence the photophysical properties and hydrogen evolution rates. H2 evolution increased dramatically by two orders of magnitude when Pt co-catalyst (1 wt.%) was incorporated, reaching an HER of 75 μmol H2/h.
