Platinum doped titanate catalysts were synthesized via alkaline hydrothermal method, followed by incipient wetness impregnation method and temperature programmed reduction (TPR). The effects of sacrificial agents on the photocatalytic activity of platinum doped titanate catalysts were studied in water splitting/alcohol photoreforming process under simulated solar light irradiation. Mechanism of photocatalytic reactions were elucidated by additional experiments performed using temperature-programmed desorption/mass spectrometry (TPD/MS). The applied alcohols (methanol, ethanol and 1-propanol) have shown enhanced hydrogen production rate in water splitting/photoreforming. Decreasing hydrogen production rate were observed in order methanol>ethanol>1-propanol (with achieved 11.6, 12.5, and 5.9 mmol g-1 h-1, respectively) due to the decrease in carbon atoms in alcohol carbon chain.
