The present study reports the versatile synthesis of photocatalysts composed of nitrogen-doped reduced graphene oxide (NrGO) flakes coated with TiO₂-FeO_x nanostructures using ultraviolet (UV) pulsed laser irradiation in a liquid environment. Different commercial graphene oxide (GO) sources were used, revealing a significant influence on the structural, compositional, and functional properties of the final photocatalysts. The H₂ production via water-splitting reaction using glycerol as sacrificial agent (photoreforming), ranged from 0.06 to 2.1 μmol H₂/g in 3.5 h depending on the GO precursor used. The best photocatalysts were those that showed a reduction in the TiO₂ material with a Ti(IV)/Ti(III) atomic ratio about 2.0–2.4, as well as a reduction and N-doping of GO, with 20–23 at % of C, and 4–6 at % of N. The light-scattering nature of the photocatalysts also had a significant effect on the H₂ production yield.
