Abstract: The invention discloses a method for synthesizing a solid catalyst with organic microsphere-loaded gold nanoparticles, which relates to a supported solid catalyst. The method provides an easy synthesis of a solid catalyst with gold nanoparticles loaded on organic microspheres as the carrier. The method includes the following steps: 1) reacting sodium with anhydrous alcohol and then a dithiol compound to obtain an ethanol solution of a dithiol sodium salt; 2) mixing methylbenzene solution of a perchloro-carbon cluster compound and the ethanol solution of the dithiol sodium salt, maintaining a constant temperature, cooling, centrifugating, and washing to obtain organic microspheres; 3) mixing the organic microspheres, chloroauric acid and a mixed reagent composed of ethanol and water, dispersing under ultrasonic conditions, adding sodium borohydride under ultrasonic conditions, stopping the ultrasonic radiation, standing, centrifugating and washing; and 4) subjecting the product of the step 3) to the treatment in the same way as the step 3) for 1-2 times, to obtain the solid catalyst with organic microsphere-loaded gold nanoparticles.
