Abstract
A synthesis process for forming nanodendrites. The nanodendrites are utilized in a process to form a heterojunction catalyst. Nanodendrites may include PtRu8 nanodendrites that can be oxidized through annealing to form PtRuO2. One heterojunction catalyst comprises PtRuO2 on a carbon support.

A method of forming a PtRuO2 heterojunction catalyst
- forming a solution of platinum precursor, a ruthenium precursor, diphenyl ether, 1,2-tetradecanediol, oleylamine, and dichlorobenzene;
- heating the solution to a reaction temperature between 230-270° C. for 5 min-1 h, forming platinum-ruthenium nanodendrites;
- separating the platinum-ruthenium nanodendrites from the solution;
- suspending the platinum-ruthenium nanodendrites in organic solvent forming a suspension;
- mixing carbon nanoparticles with the suspension;
- isolating platinum-ruthenium nanodendrites loaded with the carbon nanoparticles from the suspension;
- and
- annealing the isolated platinum-ruthenium nanodendrites loaded with the carbon nanoparticles, forming platinum-ruthenium oxide nanodendrites.
