4H/fcc heterophase platinum based nanomaterial on nanorod for electrocatalytic alcohol oxidation

A heterogeneous catalyst for alcohol oxidation reaction of an anode reaction in direct alcohol fuel cells, comprising:

• at least one Pt-based nanoisland having a 4H/face-centered cubic (fcc) heterophase and deposited on and epitaxially grown from an Au nanorod by using a synthesis process, wherein the synthesis process comprises:
• mixing a material A with a solvent B that comprises at least one selected from oleylamine and 1-octadecene to form a first mixture, wherein the material A is selected from the group consisting of platinum(II) bis (acetylacetonate), a combination of platinum(II) bis (acetylacetonate) and vanadium(III) acetylacetonate, and a combination of platinum(II) bis (acetylacetonate) and titanium oxide acetylacetonate;
• adding a dispersion C comprising 4H/fcc Au nanorods into the first mixture to form a second mixture;
• wherein an amount of the platinum(II) bis(acetylacetonate), an amount of the solvent B, and an amount of the dispersion C are positive, and a ratio of the amount of the platinum(II) bis(acetylacetonate) to the amount of the solvent B is in a range from 0.5 to 2, and a ratio of the amount of the platinum(II) bis(acetylacetonate) to the amount of the dispersion C is in a range from 2 to 6;
• heating the second mixture at a temperature in a range from 150° C. to 200° C. for a time period in a range from 5 hours to 15 hours;
• and
• recovering a 4H/fcc Pt-based heterostructure with Au from the second mixture.
