摘要

Abstract

This study is for investigating the direct electro-deoxidation ofmixed TiO

-MnO

powder to prepare TiMn

alloy in molten calciumchloride. The influences of process parameters

such as sintering temperature

cell voltage

and electrolysis time

on the electrolysis processwere examined to investigate themechanismof alloy formation. The composition and morphology of the products were analyzed by XRD and SEM

respectively. The electrochemical property of TiMn

alloywas investigated by cyclic voltammetrymeasurements. The results showthat pure TiMn

can be prepared by direct electrochemical reduction of mixed TiO

/MnO

pellets at a voltage of 3.1 V in molten calcium chloride of 900 ℃ for 7 h. The electro-deoxidation proceeds from the reduction of manganese oxides to Mn

which is reduced by TiO

or CaTiO

to formTiMn

alloy. The cyclic voltammetrymeasurements using powder microelectrode show that the prepared TiMn

alloy has good electrochemical hydrogen storage property.
