Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media
Advanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.
