AI Technical Summary
Existing additive manufacturing catalysts are prone to coating peeling and loss under fluid shear, resulting in decreased catalytic activity and failing to meet the requirements of high-speed industrial operation.
A polymerization-induced phase separation and amphiphilic ligand molecular assembly method is adopted. By complexing noble metal precursors with oleylamine, the noble metal components are migrated to the pore surface through chemical coupling and phase separation mechanical action. Multi-level pore solidification is achieved through multi-stage heat treatment to ensure the stable distribution of noble metals on the catalyst surface.
It improves the resistance of precious metal catalysts to fluid shearing and high-temperature sintering, extends the theoretical service life of the catalyst, maintains high active exposure surface and mass transfer efficiency, and is suitable for industrial waste gas treatment.
