Polyselenides on the route to electrodeposited selenium

The electrochemical oxidation of aqueous solutions of hydrogen selenide (HSe − ) and of hydrogen polyselenide ions (HSe x− ) on glassy carbon electrodes at pH = 9.2 is reported. In both cases, the oxidation leads to deposits of selenium. The role of polyselenides as intermediates in the process is d...

description The electrochemical oxidation of aqueous solutions of hydrogen selenide (HSe − ) and of hydrogen polyselenide ions (HSe x− ) on glassy carbon electrodes at pH = 9.2 is reported. In both cases, the oxidation leads to deposits of selenium. The role of polyselenides as intermediates in the process is demonstrated. At 25 °C amorphous selenium is formed whereas at 70 °C crystalline selenium is deposited. The possible use of selenium films for technological purposes is discussed.
