Rhodium carbon recovery_ Rhodium carbon recovery_ Precious metal catalyst recycling manufacturer

Rhodium carbon catalyst, also known as rhodium carbon catalyst, is an important catalyst composed of rhodium and carbon. Rhodium is a precious metal with excellent catalytic performance and chemical stability. Rhodium carbon catalysts are widely used in fields such as organic synthesis and hydrogenation reactions, with high efficiency, good selectivity, and recyclability.

There are various preparation methods for rhodium carbon catalysts, and the following will introduce two common preparation methods in detail:

The first preparation method is the physical mixing method: first, the rhodium precursor (such as rhodic acid) is mixed evenly with an appropriate amount of activated carbon or other carbon carrier materials. Then, the mixture is placed in a high-temperature furnace and calcined in an inert atmosphere. During this process, the furnace temperature is usually between 400-800 degrees Celsius, and the calcination time is usually several hours. At high temperatures, the rhodium precursor is reduced to form metallic rhodium particles, which combine with the carbon carrier to form a rhodium carbon catalyst. Finally, cool the catalyst and collect it to obtain a rhodium carbon catalyst.

2. The second preparation method is chemical deposition: first, a suitable rhodium precursor (such as rhodic acid or rhodochloric acid) is dissolved in an appropriate amount of solvent to form a solution of rhodium. Then, carbon carriers such as activated carbon and Graphite oxide are added to the solution, and they are fully mixed by stirring. Next, by adding reducing agents such as ethylene glycol, methanol, etc., the rhodium precursor is reduced to metallic rhodium. The reduction reaction is carried out at an appropriate temperature and time, usually for several hours at room temperature. After the reduction reaction is completed, the catalyst is separated from the solution and washed, dried, and other steps are taken to obtain a rhodium carbon catalyst.
