Also, the presence of W bonds remaining from the precursor delivers an enhancement within the electrical conductivity from the material. Thus, this heterojunction technique was confirmed to be a sturdy and efficient catalyst for HER in alkaline media.

This configuration guarantees additional exposure of the edge active web-sites of the WS2 and supplies an enhancement inside the charge transfer. Additionally, the presence of W bonds remaining from the precursor provides an enhancement inside the electrical conductivity from the material.
