Mo-doped cobaltous sulfide nanosheet arrays as efficient catalysts for the sulfion oxidation reaction promoting hydrogen production with ultra-low electric energy consumption

The doped Mo improves the SOR intrinsic activity of Co-based active sites in Mo–Co–S/NF; meanwhile, an advanced dissymmetrical acid-base-coupled electrolyzer is constructed to realize H 2 and S 8 production with low energy consumption.
