"The hydrogen overvoltage has been defined as the difference between the potential of the working electrode (cathode) and the theoretical reversible value for the same solution. This definition brings out the difficulty involved in the measurement of the "theoretical reversible potential for the same solution” as the potential of the hydrogen electrode in such a solution is usually different from the value of a standard reversible hydrogen electrode, for which the activity of hydrogen ions is set as being “1” and the potential arbitrarily set as being “0”. Besides, it is sometimes necessary to add addition agents to the solution to explore their influences on hydrogen overvoltage, and these addition agents may be harmful as poisons to the platinized platinum of the hydrogen electrode….
Titanium is a metal that has gained tremendous interest and increasing importance during the last decade. Various researches are still being carried on in numerous laboratories and plants to explore the properties, alloys, etc. of this metal. At the present time there is little knowledge about the hydrogen overvoltage on this metal, and it is known only that the hydrogen overvoltage is high. In view of the importance of this topic, it seemed worthwhile to investigate it to furnish some information of titanium in this aspect. It was with this intent in mind that the present research was carried out. The problem was attacked by using both impure and pure titanium in different kinds of electrolytes, with and without addition agents, and at a range of current densities"--Abstract, pages 2-3, 7-8.
