Abstract
A method of making a making a date palm syrup-graphitic carbon nitride composite is provided comprising providing a graphitic carbon nitride and a date palm syrup (DPS), heating the graphitic carbon nitride at a temperature of about 550° C., mixing the heated graphitic carbon nitride with the DPS with stirring to form a mixture such that the concentration of the DPS in the composite is in the range of 10% to 60%, and drying the mixture to form the DPS-graphitic carbon nitride composite. The DPS-graphitic carbon nitride composite is suitable for use as a photocatalyst. Also provided is a method generating hydrogen from water contacting DPS-graphitic carbon nitride composite with water with stirring in presence of light. The hydrogen generated using the method is in the region of 3210 μmol g−1 to about 7434.6 μmol g−1.
