Aerosol-assisted chemical vapor deposition of nickel sulfide nanowires for electrochemical water oxidation

Abstract

An aerosol-assisted chemical vapor-deposition (AACVD) method of making nickel sulfide (NiS) nanowires. The method includes depositing a nickel carbamate compound onto a conductive support by an AACVD technique to form nickel sulfide (NiS) nanowires on the conductive support, where the nanowires are present directly on a surface of the conductive support. The NiS electrode prepared by the process of the present disclosure showed excellent OER activity in 1.0 M KOH solution, with a low Tafel value (60 mV dec−1) and good OER stability. The NiS nanowires, as prepared, can be used in energy conversion devices such as batteries, fuel cells, and supercapacitors.
