| 摘要 |
An electrode for use in electrochemical processes is made in the form of a valve metal substrate such as titanium mesh, which carries a semiconductive intermediate coating consisting of tin and antimony oxides, advantageously laid down upon the valve metal substrate in a series of layers, and an electrocatalytically-active top coating of an oxide of manganese, applied in a series of layers of one or more thermally-decomposable manganese compounds or by the direct electrodeposition of manganese oxide, the coated or electroplated substrate subsequently being baked in an oxidizing atmosphere at a temperature in the range of 380 DEG to 420 DEG C so as to convert the one or more compounds or the electro-deposited oxide to an electrocatalytically-active form of an oxide of manganese. |
