Synthesis and structure-activity relationship exploration of carbon-supported PtRuNi nanocomposite as a CO-tolerant electrocatalyst for proton exchange membrane fuel

Article Abstract:

A carbon supported PtRuNi nanocomposite is synthesized through a microwave-irradiated polyol plus annealing synthesis strategy. It is suggested that the improved Co-tolerant performance of the PtRuNi nanocomposite should be related to the hydrogen spillover on the catalyst surface, the enhanced oxidation of [Co.sub.ads] by nickel hydroxides, and the high proton and electronic conductivity of the hydroxides.

Synthesis and characterization of ultrathin W[O.sub.3] nanodisks utilizing long-chain poly(ethylene glycol)

Article Abstract:

The synthesis of ultrathin W[O.sub.3] nanodisks using a wet chemical route with poly(ethylene glycol) (PEG) as a surface modulator is described. The large flat surface area and high aspect ratio of the W[O.sub.3] nanodisks are useful in photoelectrochemical (PEC) cells for hydrogen production through direct water splitting.
