monolayer approach, indicates that its small natural abundance should not limit its
applications.
Furthermore, the monolayer electrocatalyst approach can facilitate the application of electrocatalysts based on very rare noble metals such as Os, Ir [3], and Pd [4]
where price and inadequate stability have limited their applications in the past. The
use of alkaline electrolyte solutions and nonaqueous solvents with these noble metals will help create novel electrocatalysts that will benefit from the specific metal
properties. Increased catalyst selectivity can be expected from these new catalysts
and will be a very important feature of these syntheses.
