Abstract

Polycrystalline SnS_x (p-SnS_x) nanofilms are capable of yielding formate with a maximum faradaic efficiency of 97% and high stability over 50 h. Moreover, when tested in a membrane electrode assembly cell, p-SnS_x has a high faradaic efficiency in a broad partial current density range (100-420 mA cm^-2) for formate production.
