Graphitic carbon nitride (g-C3N4) is a two-dimensional (2D) polymeric semiconductor that has received attention due its excellent photocatalytic properties especially toward hydrogen production under solar illumination. The band-gap of g-C3N4 is 2.7 eV, resulting in light absorption of a wide range of the visible light spectrum. It however, suffers from fast recombination of photoinduced electrons and holes which affects its efficiency as a photocatalysts. Recent research have shown that 2D/2D heterojunctions constructed from g-C3N4 and transition metal sulfides could improve the charge separation. In this seminar, we present results on the effect of embedded, metal and non-metal, atoms on the charge transfer in the g-C3N4/MoS2 heterojunction
