Rhodium–Tin Binary NanoparticleA Strategy to Develop an Alternative Electrocatalyst for Oxygen Reduction
A Rh–Sn nanoparticle
is achieved by combinatorial approaches
for application as an active and stable electrocatalyst in the oxygen
reduction reaction. Both metallic Rh and metallic Sn exhibit activities
too low to be utilized for electrocatalytic reduction of oxygen. However,
a clean and active Rh surface can be activated by incorporation of
Sn into a Rh nanoparticle through the combined effects of lateral
repulsion, bifunctional mechanism, and electronic modification. The
corrosion-resistant property of Rh contributes to the construction
of a stable catalyst that can be used under harsh fuel cell conditions.
Based on both theoretical and experimental research, Rh–Sn
nanoparticle designs with inexpensive materials can be a potential
alternative catalyst in terms of the economic feasibility of commercialization
and its facile and simple surfactant-free microwave-assisted synthesis
