| titleOfInvention | Preparation method of palladium hydroxide carbon carrier catalyst |
| abstract | The invention discloses a preparation method of a palladium hydroxide carbon carrier catalyst, which comprises the following steps: firstly, adding palladium acetate into acetone to form a palladium solution, soaking activated carbon in the palladium solution, performing ultrasonic treatment, filtering and drying; and then adding the highly-substituted hydroxypropyl cellulose into a methanol solution, then injecting the methanol solution into pores of the coated activated carbon by adopting a soaking perfusion method, drying, repeatedly perfusing to obtain activated carbon with the pores blocked, then soaking in a sodium hydroxide solution and continuously stirring, drying, soaking in methanol again, drying, repeatedly soaking in sodium hydroxide and methanol for 3-5 times, cleaning, and drying to obtain the palladium hydroxide carbon carrier catalyst. The method can fully dissolve out the high-substituted hydroxypropyl cellulose filled in the pores of the activated carbon through multiple reactions from outside to inside, so that the exposed palladium is converted into palladium hydroxide step by step, and the palladium can be uniformly distributed on the inner surface and the outer surface of the carbon carrier to form uniform active metal component distribution. |
