Rhodium on Carbon

Chemical properties

Rhodium carbon is insoluble in acidic solutions, but soluble in aqua regia. It has unique selectivity and high activity, and can make reactions proceed at low temperature, low pressure, and even at room temperature and pressure‌.

Main Specification:

Rhodium content: 0.1% ~ 30%

Carrier material: coconut shell, coal, wood, peat and so on

Carrier state: powdered activated carbon

Specific surface area (m2/g): ≥930

Metal surface area (m2/g): 85 ~ 105

Application areas

Rhodium carbon is mainly used as a catalyst and is widely used in the following fields:

‌Organic synthesis‌: used to prepare compounds such as 4-cyclohexylproline, 3-oxa-8-aza-bicyclo[3.2.1]octane hydrochloride‌.

‌Medicine and pesticides‌: It has important applications in fine chemical fields such as medicine and pesticides‌4.

‌Electronic industry‌: used to manufacture electronic components such as capacitors and resistors, with good conductivity and stability‌.

‌Automobile exhaust purification‌: used for automobile exhaust purification to reduce harmful gas emissions‌. Preparation method

The preparation method of the rhodium carbon catalyst includes the following steps:

The carrier activated carbon is washed with water and acid.

The rhodium compound solution and calcium hypochlorite are mixed and then impregnated or sprayed on the activated carbon.
