Enhancing by Weakening: Electrooxidation of Methanol on Pt3Co and Pt Nanocubes

Enhancing by weakening: electrooxidation of methanol on Pt3Co and Pt nanocubes.

Methanol and CO electrooxidation

The methanol oxidation reaction has been the subject of a large number of studies in the past.[1, 2] Early work revealed a complex reaction mechanism,[3–6] indicating the electrocatalysis of methanol oxidation as the most difficult task in the realization of a direct methanol fuel cell (DMFC). Several metal catalysts were proposed for the reaction, most of them based on modifications of Pt with...

Ternary Pt-Ru-Ni catalytic layers for methanol electrooxidation prepared by electrodeposition and galvanic replacement

Ternary Pt-Ru-Ni deposits on glassy carbon substrates, Pt-Ru(Ni)/GC, have been formed by initial electrodeposition of Ni layers onto glassy carbon electrodes, followed by their partial exchange for Pt and Ru, upon their immersion into equimolar solutions containing complex ions of the precious metals. The overall morphology and composition of the deposits has been studied by SEM microscopy and ...

Synthesis of Pt nanopetals on highly ordered silicon nanocones for enhanced methanol electrooxidation activity.

Platinum (Pt) nanopetals were electrodeposited on highly ordered silicon nanocones (SiNCs) and explored as the electrocatalyst for methanol oxidation reaction (MOR) for direct methanol fuel cells applications. Highly ordered SiNCs array fabricated using the porous anodic aluminum oxide as the template had a high surface area. Well-dispersed Pt nanopetals possessing high electrocatalytic surface...

Well-dispersed high-loading pt nanoparticles supported by shell-core nanostructured carbon for methanol electrooxidation.

Shell-core nanostructured carbon materials with a nitrogen-doped graphitic layer as a shell and pristine carbon black particle as a core were synthesized by carbonizing the hybrid materials containing in situ polymerized aniline onto carbon black. In an N-doped carbon layer, the nitrogen atoms substitute carbon atoms at the edge and interior of the graphene structure to form pyridinic N and qua...
