Electrocatalytically Activated, Dimensionally Stable Chlorine-Evolving Electrodes

Electrocatalytically Activated Dimensionally Stable Chlorine-Evolving Electrodes 

Chloralkalielectrolysis was technically executed more than 100 years ago. The anodic reaction 

In 1958, Henry Beer invented the dimensionally stable anode (19. 20), which consisted of a titanium anode covered with a catalytic layer composed mainly of a mixture of Ti02 and Ru02. Due to the joint efforts of Beer and of the De Nora Company, the dimensionally stable chlorine anode became accepted everywhere and its introduction revolutionized the technology (4) of chloralkali electrolysis. 

In particular, the exchange of the amalgam technology by membrane technology, which initially was enforced in Japan by legislation (1976 to 1986), profited from the already existing technology of anodic Cl2 evolution at DSAs (21).
