Effects of redox state of PtRu electrocatalysts on methanol oxidation activity
Article Abstract:
A study is conducted to establish the relative methanol oxidation activity of PtRu catalysts in well-characterized reduced, as-received, oxidized, and strongly oxidized states, using a consistent experimental approach. The findings indicate that samples supported using acetic acid are more active than those supported by Nafion, but are less stable and more suspectible to change in catalyst state from heat gun drying.

Triarylphosphine-stabilized platinum nanoparticles in three-dimensional nanostructured films as active electrocatalysts
Article Abstract:
A reproducible synthesis of platinum nanoparticles (Pt NPs) stabilized with a water-soluble phosphine was developed by ligand exchange with preformed gylcol-stabilized platinum nanoparticles. Complete reduction of oxygen by four electrons is achieved with 4 layers of TPPTP-Pt NPs and a total Pt loading of 5.6 mug/[cm.sup.2].

How to make electrocatalysts more active for direct methanol oxidation-avoid PtRu bimetallic alloys!
Article Abstract:
A mixed -phase electrocatalyst containing Pt metal and hydrous ruthenium oxides (RuO2H (sub y)) is found to be a more desired form of catalyst as compared to the Pt-Ru electro catalyzed oxidation of methanol. The active catalyst is discovered to be able to oxidize methanol fully to carbon dioxide and water.
