The Frumkin era in electrochemistry

Alexander Naumovich Frumkin (1895–1976) founded and led one of the twentieth century’s largest research schools in the field of electrochemistry. Here, a brief attempt is made to sketch, in rather large brushstrokes, the main outlines of his life and work and to summarize the many and varied contributions that he made to this rapidly developing field

Intensification of the nitrate anion reduction on a membrane palladium electrode

Polarization curves of electroreduction of nitrate anions in sulfuric acid aqueous solutions on a Pd/Pd palladium electrode with the opposite side kept at different constant potentials in the region of Pd-H α-phase formation are compared. The reduction rate of nitrate anions is shown to be substantially higher on a membrane electrode, provided the conditions of hydrogen supply from the membrane's opposite side to the reaction zone are realized. This phenomenon is caused by the reduction of a chemisorbed intermediate (a certain N(III) form) by hydrogen diffused through the membrane. It is shown that the measurements of hydrogen diffusion currents through a membrane can be used in plotting hydrogen sorption isotherms in the Pd-H α-phase
