Zusammenfassung:	The invention discloses a preparation method for a CQDs/GCNNs/Fe(2-x)TixO3/FTO photo-anode. The preparation method comprises the steps that soluble trivalent molysite and urea are put in a hydrothermal environment with an organic titanium solution as a titanium source and FTO conducting glass as a carrier, so that Fe(2-x)TixO3/FTO is prepared; and then, the Fe(2-x)TixO3/FTO is treated through thetreatment method as specified, so that the CQDs/GCNNs/Fe(2-x)TixO3/FTO photo-anode is obtained. The photoelectricity test indicates that after the prepared photo-anode is treated through the treatmentprocess, the photoelectric current density of CQDs/GCNNs/Fe(2-x)TixO3/FTO is 3.38 mA/cm at the voltage of 1.23 V relative to a reversible hydrogen electrode, the photoelectric current density of the Fe(2-x)TixO3/FTO is 1.66 mA/cm at the voltage of 1.23V relative to the reversible hydrogen electrode, and the photoelectric current density is increased by two times or more; and therefore, thephoto-anode and the treatment met
