ABSTRACT
This chapter primarily summarizes the recent advances in PtSn-
based nanomaterials for direct alcohol fuel cells, such as PtSn-
based trimetallic, oxides (TiO2, SnO2, and CeO2)-doped bi-and
trimetallic PtAu, and graphene/graphyne as supporting materials
for the electrocatalysts of ethanol electro-oxidation reaction. The
activity of the electrocatalyst PtSn could also vary with a few factors,
like composition (Pt:Sn ratio), degree of alloying, roughness and
size of particles, pH, as well as characteristics of electrolytes. These
effects on the activity of the electrocatalyst and some open questions
arising from experiments are also discussed.
