Development of highly efficient resin-based Ag–π nanocatalysts via an in situ catalytic strategy for selective cinnamaldehyde hydrogenation

This study presents ion-exchange resin-based Ag-π nanocatalysts synthesized via an in situ catalytic strategy. Ag/RS-180 demonstrates 100% conversion and selectivity for cinnamaldehyde hydrogenation, while Ag/RS, lacking π-carbon, exhibits only 5-12% conversion. The local conjugated network functions as an efficient electron pool, donating electrons to facilitate the reduction of cinnamaldehyde.
