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 100Ω. 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.

Abstract: A linear motor motion control method, device, equipment and storage medium. The proposed invention uses an extended state observer constructed in advance based on the model parameters of the linear motor, and performs state estimation based on the total control amount of the linear motor and the actual displacement signal to obtain each observation signal.
