Abstract:
PtSnZn nanosheet thin film with stable and high activity towards methanolelectro‐oxidation was synthesized via a simple reduction of organometallicprecursors including [PtCl2(cod)] (cod = cis,cis‐1,5‐cyclooctadiene) and[Sn(CH3)4] complexes, in the presence of [Zn(acac)2] (acac = acetylacetonate)complex at toluene–water interface. Catalytic activities of PtSnZn nanosheetswere investigated in the p‐nitrophenol (p‐Nip) reduction and methanol oxidationreactions. The obtained results demonstrate that PtSnZn nanosheetsexhibit a good electrocatalytic performance for methanol oxidation reaction,the catalytic activity of the PtSnZn nanosheets being at least 3.5 times higherthan that of Pt nanoparticle thin film. Also, the apparent rate constantobtained for p‐Nip reduction with the PtSnZn nanosheets is at least 2.3 timeshigher than that for Pt nanoparticle thin film due to the appropriate interactionbetween platinum, tin and zinc metals and geometric properties ofPtSnZn nanosheet thin film. Nanosheets are highly favourable for superiorcatalytic performances due to their geometric properties. A facile and efficientroute was used to synthesize trimetallic alloy thin film at oil–water interface.
