Application of differential electrochemical mass spectrometry to the electrocatalytic oxidation of formic acid at a modified Bi/Pt electrode surface

The design and construction of a differential electrochemical mass spectrometry system is presented. This system has been employed in the study of the reaction products and intermediates during the electrocatalytic oxidation of formic acid on Pt(111) and deliberately stepped platinum surfaces, modified with irreversibly adsorbed Bi (Biad).
