Title:
NITROGEN-PHOSPHORUS-MODIFIED GRANULAR CARBON-SUPPORTED BIMETALLIC CATALYST, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/104437
Kind Code:
A1
Abstract:
Provided are a nitrogen-phosphorus-modified granular carbon-supported bimetallic catalyst, a preparation method therefor 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.
