PtM/CNT (M = Mo, Ni, CoCr) Electrocatalysts with Reduced Platinum Content for Anodic Hydrogen Oxidation and Cathodic Oxygen Reduction in Alkaline Electrolytes
نویسندگان
چکیده
Bimetallic catalysts containing platinum and transition metals (PtM, M = Mo, Ni, CoCr) were synthesized on carbon nanotubes (CNTs) functionalized in an alkaline medium. Their content is 10–15% by mass. PtM/CNTNaOH are active both the hydrogen oxidation reaction (HOR) oxygen reduction (ORR) electrolytes. Although based a single metal inactive HOR, their activity cathode process of ORR increases relative to CNTNaOH. When using rotating ring-disk electrode method for ORR, PtM/CNT showed high selectivity reducing directly water. In catalyst had comparable that commercial monoplatinum catalyst. The results obtained show it possible use fuel cell as anode cathode.

Single Platinum Atoms Electrocatalysts: Oxygen Reduction and Hydrogen Oxidation Reactions
Atomically dispersed catalyst consisting of Pt atoms arranged in a c(2 × 2) array on RuO2(110) substrate was prepared. A large interatomic distance of Pt atoms in a c(2 × 2) phase precludes the reactants to interact with more than one Pt atoms. A strong bond of Pt atoms with RuO2 prevents agglomeration of Pt atoms to form 2D-islands or 3D-clusters. Activities of single Pt atom catalyst for the ...
متن کاملPlatinum Monolayer Electrocatalysts for Anodic Oxidation of Alcohols.
The slow, incomplete oxidation of methanol and ethanol on platinum-based anodes as well as the high price and limited reserves of Pt has hampered the practical application of direct alcohol fuel cells. We describe the electrocatalysts consisting of one Pt monolayer (one atom thick layer) placed on extended or nanoparticle surfaces having the activity and selectivity for the oxidation of alcohol...
متن کاملPerovskite Electrocatalysts for the Oxygen Reduction Reaction in Alkaline Media
Oxygen reduction is considered a key reaction for electrochemical energy conversion but slow kinetics hamper application in fuel cells and metal-air batteries. In this review, the prospect of perovskite oxides for the oxygen reduction reaction (ORR) in alkaline media is reviewed with respect to fundamental insight into activity and possible mechanisms. For gaining these insights, special emphas...
متن کاملIn situ activation of a Ni catalyst with Mo ion for hydrogen evolution reaction in alkaline solution
In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...
