We demonstrate a facile and efficient method for the synthesis of a metal-doped WS₂ nanoflower (NF) catalyst. We also report its application for the electrocatalytic hydrogen evolution reaction (HER). The flower-like WS₂ particles were produced by a hydrothermal reaction, and, subsequently, the WS₂ was doped with metal chlorides such as AuCl₃, AgCl, PtCl₂, and PdCl₂, followed by reduction with sodium borohydride to form metal-doped WS₂ NFs. The Pd-doped WS₂ NF catalyst showed a high HER performance, having a Tafel slope of 54 mV/dec and an overpotential of -175 mV at −10 mA cm⁻². The improvement is attributed to the energy band alignment near the H⁺/H₂ reduction potential and the large surface area of the WS₂ NFs.
