· Mg1 V4 S8

Mg₁V₄S₈ is a layered transition metal sulfide semiconductor compound combining magnesium, vanadium, and sulfur in a mixed-valence structure. This is a research-phase material investigated for its potential in energy storage, catalysis, and optoelectronic applications, with particular interest in its layered crystal structure that resembles other two-dimensional (2D) materials. Compared to graphene and transition metal dichalcogenides (TMDs), vanadium sulfides offer tunable electronic properties and redox-active sites, making them candidates for battery cathodes, electrochemical catalysts, and photoelectrochemical devices, though commercial adoption remains limited.
