Abstract

We report a general strategy for the fabrication of binder-free, flexible and weavable transition-metal dichalcogenide nanosheet-based hybrid fibers by using well-aligned multi-walled carbon nanotubes as hosts. The resulting hybrid fibers are used as electrodes for electrocatalytic hydrogen evolution, showing excellent performance in both acidic and basic environments, and excellent long-term stability.
