Facile preparation of Pd-Au bimetallic nanoparticles via in-situ self-assembly in reverse microemulsion and their electrocatalytic properties

- Pd-Au nanoparticles were prepared on Ni via self-assembly in microemulsion.
- Pd-Au bimetallic nanoparticles dispersed uniformly with a narrow size distribution.
- The growth mechanism of Pd-Au nanoparticles in microemulsion was explored.
- The nanoparticles had good catalytic activity and stability for ethanol oxidation.
