Abstract: This application discloses a silicon carbide (SiC)-loaded graphene photocatalyst for hydrogen production under visible light irradiation and a preparation method thereof. Pure SiC and pure black carbon are respectively prepared and mixed to obtain a mixture with a resistance less than 100?. Then the mixture was vacuumized and processed with a current pulse with an increasing voltage until a breakdown occurs, and subjected to ultrasonic stirring, centrifugal washing and vacuum drying in turn to obtain the SiC-loaded graphene photocatalyst. By means of the current pulse, a heterojunction is formed between SiC and graphene to improve the catalytic activity of the photocatalyst; and the photocatalytic hydrogen production rate of SiC nanoparticles can be enhanced after loaded on the graphene.
