1. A method for preparing a silicon carbide (SiC)-loaded graphene photocatalyst for hydrogen production under visible light irradiation, comprising:
step (A) preparing a pure SiC;
step (B) preparing a pure black carbon;
step (C) mixing the pure SiC and the pure black carbon to obtain a mixture, wherein the mixture has a resistance less than 100 Ω;
step (D) feeding the mixture to a current pulse processing equipment; and vacuumizing the current pulse processing equipment, and processing the mixture with a current pulse with an increasing voltage until a breakdown of the mixture occurs, wherein the current pulse has a capacitance of 70-80 mF and a voltage of 120-180 V; and
step (E) subjecting the mixture to ultrasonic stirring, centrifugal washing and vacuum drying in turn to obtain the SiC-loaded graphene photocatalyst.
