Impact of a conductive oxide core in tungsten sulfide-based nanostructures on the hydrogen evolution reaction†
Abstract
Tungsten oxide/tungsten sulfide (W18O49@WS2) core–shell nanorods prepared via a controlled sulfidization reaction of W18O49 nanowhiskers showed hydrogen evolution reaction (HER) activity superior to WS2 nanotubes, indicating the critical role of a highly conductive oxide core in enhancing HER activity.
