“…As a cheap organic compound and easy to produce on a large scale, urea can form low-melting molten salts with alkali metal halides characterized with high conductivity and wide electrochemical window ( Liang et al, 2001 ; Liu et al, 2017 ). At present, there are a few reports on the preparation of active metals and their alloys by electrodeposition in urea-based room temperature molten salts ( Liu et al, 2006 ; Wang et al, 2008 ; Li et al, 2009 ).…”
