چکیده انگلیسی


• Thin film organometallic polymer hydrogels of poly(ferrocenylsilanes) are described.
• Pre-crosslinked gels with controlled thickness are covalently coupled to substrates.
• Metal nanoparticles prepared in-situ from metal salts in the hydrogels are reported.
• Pd metal nanoparticles obtained in-situ are used in electrocatalysis.

Redox responsive hydrogel thin films consisting of poly(ferrocenyl(3-bromopropyl)methylsilane) were fabricated by crosslinking the polymer with N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA). Owing to the presence of ferrocene in the redox-active PFS chains, the thin hydrogel films could be oxidized and reduced chemically and electrochemically. The thin films could be used as a reducing environment for the in-situ formation of Pd nanoparticles, yielding PFS hydrogel-nanoparticle composites, which were employed directly in the electrocatalytic oxidation of ethanol. Pronounced catalytic activity of the Pd-loaded hydrogel films was observed.
