| abstract |
The invention discloses a preparation method of a high-efficiency photocatalyst, which is characterized by comprising the following steps: step S1, ionizing 4,4' -bis [4- (di-p-tolylamino) styryl ] biphenyl with 4- (chloromethyl) benzophenone; step S2, ionizing hyperbranched poly (1, 5-diaminoanthraquinone) by m-cyanobenzyl chloride; and step S3, forming the photocatalyst. The invention also provides the high-efficiency photocatalyst prepared by the preparation method of the high-efficiency photocatalyst. The high-efficiency photocatalyst provided by the invention has the advantages of wider visible light response range, higher photocatalytic activity, better stability, longer active life and lower manufacturing cost. |
