A facile approach to fabricate free-standing hydrogen evolution electrodes: riveting tungsten carbide nanocrystals to graphite felt fabrics by carbon nanosheets†
Abstract
We report a novel three-dimensional architecture, consisting of tungsten carbide nanocrystals which are intimately riveted to graphite felt fabrics by carbon nanosheets (CNS@WC/GF). The as-prepared CNS@WC/GF monolith is utilized as a binder-free hydrogen evolution reaction electrode in both acidic and alkaline solutions. It demonstrates remarkable activity as well as durability.
