One-dimensional noble metal electrocatalysts: a promising structural paradigm for direct methanolfuelcells

Koenigsmann, Christopher, Wong, Stanislaus S.·2011·Energy Environ. Sci.

Abstract

In this perspective, the catalytic shortfalls of contemporary DMFCs are discussed in the context of the materials that are currently being employed as electrocatalysts in both the anode and cathode. In light of these shortfalls, the inherent advantages of one-dimensional (1D) nanostructures are highlighted so as to demonstrate their potential as efficient, robust, and active replacements for contemporary nanoparticulate electrocatalysts. Finally, we review in detail the recent applications of 1D nanostructured electrocatalysts as both anodes and cathodes, and explore their potentially promising results towards improving DMFC efficiency and cost-effectiveness. In the case of cathode electrocatalysts, our group has recently prepared both 200 nm platinum nanotubes and ultrathin 2 nm platinum nanowires, which evinced two-fold and seven-fold enhancements in area specific ORR activity, respectively, as compared with contemporary commercial Pt nanoparticles. Similarly, the development of one-dimensional anodic electrocatalysts such as alloyed PtRu and PtCo nanowires, hierarchical Pt~Pd nanowires, and segmented PtRu systems have yielded promising enhancements towards methanol oxidation.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • One-dimensional nanostructures can allay aggregation, dissolution, and Ostwald ripening that NPs frequently face.

    “these nanostructures can allay the aggregation, dissolution, and Oswald developing that the NPs frequently face by.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
