Abstract

A composition for oxidizing dimethyl ether includes an alloy supported on carbon, the alloy being of platinum, ruthenium, and palladium. A process for oxidizing dimethyl ether involves exposing dimethyl ether to a carbon-supported alloy of platinum, ruthenium, and palladium under conditions sufficient to electrochemically oxidize the dimethyl ether.

Claims (5)

1. A composition, consisting essentially of:

carbon; and

Pt 60 Ru 15 Pd 25 supported on the carbon, wherein the composition catalyzes an oxidation of dimethyl ether.

2. The composition of claim 1 , wherein a metal loading value associated with the composition is between 22% and 26%.

3. The composition of claim 1 , wherein a metal loading value associated with the composition is 24%.
