An efficient strategy for simultaneous gold deposition and obtention of hierarchical Au/TS-1 applied to liquid-phase propylene epoxidation

A novel and straightforward one-step method has been developed for the controlled deposition of gold nanoparticles (AuNPs) with uniform diameters onto the titanosilicate (TS-1) zeolitic surface via a direct anionic exchange (DAE) approach. This innovative process simultaneously introduces auxiliary mesoporosity into the zeolite framework, overcoming critical limitations associated with traditional microporous catalysts, including diffusion constraints…
