Synergistic W and V Doping Induce Defects and Thus a High Catalytic Surface Area in MoS2 for the Hydrogen Evolution Reaction

European Journal of Inorganic Chemistry, EarlyView.
Double doping with V and W of hydrothermal microwave‐grown MoS2 enhances the density of structural defects. It improves the ECSA and shifts the surface chemistry to an oxysulfide‐rich environment. The resulting VW‐doped MoS2 nanoflowers thus demonstrate robust electrocatalysis of hydrogen evolution.

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

Small, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...
