Mo₂TiC₂/WSe₂ nanoarchitectures: in situ grown nanoflowers for efficient hydrogen electrocatalysis

The combination of 2D materials provides a powerful strategy to enhance electrocatalytic hydrogen evolution. Efficient hydrogen electrocatalysis is achieved by interfacing conductive Mo₂TiC₂ MXene with catalytic WSe₂ nanoflowers via a one-step hydrothermal route. The hybrid exhibits low overpotential, fast charge transfer, and long-term stability, outperforming pristine components and establishing Mo₂TiC₂/WSe₂ as a promising hydrogen evolution reaction platform.
