•Se-modified g-C3N4 has been synthesized from melamine cyanurate and SeO2.•Condensation temperature remarkably changes the properties of the g-C3N4 samples.•Incorporation of 1 wt.% Pt co-catalyst significantly improves H2 evolution.•An HER of 75 μmol H2/h is attained for the 650°C-treated sample for λ > 455 nm.
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.
