Provided are a nitrogen-phosphorus-modified granular carbon-supported bimetallic catalyst, a preparation method thereof and the use thereof. The catalyst comprises a nitrogen-phosphorus-modified carbon carrier and metal particles supported on the carbon carrier. The metal particles include first metal elementary substance particles, second metal elementary substance particles and bimetallic alloy phase particles. The percentage of the bimetallic alloy phase particles in the metal particles is ≥80%, and at least 90% of the alloy phase particles have a size of 1 nm to 20 nm. The catalyst has advantages such as a high proportion of alloy phase particles, a uniform particle size distribution, a high metal utilization rate, low costs, high stability and a high catalytic activity.

Nitrogen-phosphorus-modified granular carbon-supported bimetallic catalyst, preparation method therefor and use thereof

A sulfur-containing palladium-carbon catalyst prepared by loading palladium on an active carbon, mixing the palladium-carbon catalyst with a solvent to form a slurry, adding a sulfide to the slurry to treat the loaded palladium under a predetermined temperature, and removing liquid and drying to obtain the catalyst. The sulfur-containing palladium-carbon catalyst is suitable for making phenylene diamine rubber antioxidant with improved productivity and selectivity.
