Catalytic activity of silver-ion exchanger nanocomposites in methanal oxidation reaction with molecular oxygen

摘要

Silver-containing ion exchangers with the surface distribution of silver nanoparticles-promising catalytic materials for the methanal oxidation reaction-have been synthesized by chemical deposition of the metal onto ion-exchange matrices. The resulting materials are evidently superior to the available analogues in that they allow one to carry out the reaction with the high conversion (80-90%) at low temperature and have a high capacity to OH- ions, which play a key role in the oxidation of an aldehyde to gaseous products (CO and CO2).
