▎ 摘　　要

NOVELTY - Preparing graphene-carbon nanotube molecular framework photocatalyst comprises (i) preparing graphene oxide, (ii) preparing carbon oxide nanotubes, (iii) preparing tetrabutyl titanate solution with concentration of 0.5-0.8x 10-2 mol/l with absolute ethanol as solvent, (iv) adding 0.01-0.05 g graphene oxide prepared in step (i) into reactor, then adding 3-5 mu l tetrabutyl titanate solution prepared in step (iii) into reactor and then reacting at 100-150 degrees C for 6-8 hours and (v) adding carbon oxide nanotubes obtained in step (ii) into 0.5-1 mol/l strong sodium oxide solution after completing the reaction in step (iv) and then reacting at 60-65 degrees C for 8-12 hours. USE - The method is useful for preparing graphene-carbon nanotube molecular framework photocatalyst. ADVANTAGE - The photocatalyst: has excellent purification effect on indoor pollutants including formaldehyde, and long-lasting purification ability; and does not cause secondary pollution.
