Pt3Sn nanoparticles enriched with SnO2/Pt3Sn interface for highly efficient alcohol electrooxidation

The Pt3Sn nanoparticles (NPs) enriched with Pt3Sn/SnO2 interfaces (Pt3Sn@u-SnO2/NG) were achieved through thermal treatment of Pt2Sn/NG in H2 atmosphere, followed by annealing under H2 and air conditions. The unique structure...

Preparation of Carbon-Supported Ternary Nanocatalysts Palladium-Vanadium-Cobalt for Alcohol Electrooxidation

Carbon-supported nanocatalysts palladium-vanadium-cobalt (PdVCo) were synthesized via ethylene glycol (EG) reduction reaction and NaBH4-assisted reduction. The electrocatalytic performance for alcohol oxidation in alkaline solutions was investigated. The XRD and EDX results confirmed the incorporation of V and Co with Pd lattice to form the ternary nanocatalysts PdVCo in a single phase. The NaBH4-assisted EG reduction process exhibited highly dispersed nanoparticles with a uniform size, and the electrochemical surface area (ECSA) determined by cyclic voltammetry in 1 M KOH was also superior. In electrocatalysis performance, the cyclic voltammetry (CV) and chronoamperometry (CA) results presented an excellent electrocatalytic activity and stability of the PdVCo-20EG-20NaBH4 sample in the alcohol electrooxidation as compared to other synthesized samples with the steady current of 52 mA/cm2 and 21.9 mA/cm2 in methanol and ethanol, respectively.

High-performance alcohol electrooxidation on Pt3Sn–SnO2 nanocatalysts synthesized through the transformation of Pt–Sn nanoparticles

An ordered Pt3Sn intermetallic, in which every Pt3Sn NP is in contact with one or more SnO2 NPs, was synthesized by the in situ transformation of Pt–Sn/NG.

Tiny Ir doping of sub-one-nanometer PtMn nanowires: highly active and stable catalysts for alcohol electrooxidation

We proposed a facile yet rational strategy to synthesize tiny Ir-doping PtMn 1D ultrathin NWs at an atomic level. The composition-optimized Pt74Mn21Ir5 NWs showed superior electrocatalytic performance for EOR and MOR.
