## Abstract

In this paper, we discuss the effect of Pb, Cd, Ni, Zn, and Mn adatoms on the rate of methanol oxidation at the Pt electrode in the carbonate solution. In Na2B4O7, the presence of Cd, Ni, Mn, and Zn adatoms increased the electrocatalytic current density while the presence of Pb inhibits the methanol oxidation.
