Synthesis and characterization of nanostructured electrocatalysts based on nickel and tin for hydrogen peroxide electrogeneration

- 9% SnNi/C 6:1 was the best choice for H2O2 electrogeneration among all materials.
- 9% SnNi/C 6:1 transferred 2.2 electrons and had a H2O2 percentage efficiency of 88%.
- X-ray diffraction analysis identified a phase for 9% SnNi/C 6:1 (Ni3Sn4).
- Ni3Sn4 is a structure tolerant of defects that can increase oxygen diffusion.
