Industrial Electrochemistry – Safe, Clean, Green

By Gerhard Kreysa and Klaus Jüttner, Dechema e.V. |

    The highly diversified field of industrial electrochemistry includes processes to synthesize organic and inorganic compounds, the conversion and storage of energy, galvanic deposition of metals and alloys. Electrochemistry also plays a lead role in corrosion protection, sensor devices, and other kinds of technology where charge transfer takes place at an electrified interface. Today, research is becoming more and more specialized to particular problems of multidisciplinary character related to chemistry, physics, biology, medicine, electronics, and materials science. Electrochemical surface technology has become a key issue, since almost any commercial product undergoes some kind of surface treatment to improve its appearance, functionality and properties. Electrochemical engineering deals with the development and optimization of electrochemical processes based on the fundamental laws of electrochemistry and chemical engineering. Today, prevailing industrial-scale processes include the electrolysis of salt solutions to produce chlorine and sodium hydroxide (chlor-alkali) and related processes of chlorate and hypochlorite formation, and the production of peroxodisulfate and hydrogen peroxide. The electrowinning and refining…
