Abstract
Disclosed are a Z-type heterojunction composite material of a tungsten oxide nanorod/a titanium carbide quantum dot/an indium sulfide nanosheet, a preparation method therefor and an application thereof. The method includes: preparing a titanium carbide quantum dot by using freeze-thaw and ultrasound methods for multiple times, and then placing a tungsten trioxide nanorod prepared by a hydrothermal method into a titanium carbide quantum dot aqueous solution, stirring same, and then standing same to obtain a tungsten oxide nanorod loading a quantum dot; stirring and uniformly mixing an indium compound and a sulfur compound in an ethylene glycol solvent, and then adding the tungsten oxide nanorod loading the quantum dot, and performing a reflux reaction at constant temperature to obtain the composite material. The titanium carbide quantum dot of the present invention can provide good electron transport channels at different semiconductor interfaces.
