The development of photocatalysts is increasingly directed towards achieving high activity, stability, affordability, and non-toxicity. Solar-driven photoreforming of oxidized cellulose and plastics (PET, PVC, PMMA, PP, and PS) represents an innovative approach to converting biomass into hydrogen (H₂) fuel, supporting environmental sustainability by mitigating plastic pollution. Graphitic carbon nitride (g-C₃N₄) has gained attention as a viable polymeric semiconductor for visible-light-driven photocatalysis. In this study, bulk g-C₃N₄ was synthesized through thermal polymerization, and a 3-nm-thick g-C₃N₄ nanosheet (NS) was obtained via ultrasonic agitation. To boost photocatalytic performance, different weight percentages of Pt were deposited on g-C₃N₄ NS as cocatalysts. The 3.0 wt% Pt-loaded g-C₃N₄ NS demonstrated enhanced solar-driven activity attributed to the intramolecular synergistic effect. For hydrogen production through the photoreforming of plastic, the 3.0 wt% Pt-loaded g-C₃N₄ NS achieved a maximum hydrogen production rate of 7960.41 μmol g^-1 when processing PET plastic.
