General description

Bis(ethylenediamine)copper(II) hydroxide solution is a stable complex formed by copper (Cu) ions with ethylenediamine. It is a transition metal solution that can be used as a catalyst for electrochemical reduction process.

Application

Bis(ethylenediamine)copper(II) hydroxide has been used to evaluate cation exchange capacity (CEC) of clays by copper absorption.
Copper(II) ethylenediamine complex may be used to evaluate the cation exchange capacity (CEC) of clay materials. It may also be used to modify polyoxoniobate, which is a class of polyoxometalates (POMs) that finds potential application in photocatalytic H2 production.
