Effect of van der Waals stacking in CdS monolayer on enhancing the hydrogen production efficiency of SiH monolayer

“…10,11 Several studies have been undertaken since the discovery of graphene to examine potential two-dimensional (2D) photocatalysts for water splitting, [12][13][14] such as MXenes, Janus MAB (M = Mo and W; A and B = S, Se and Te), graphitic carbon nitrides (g-C 6 N 6 , g-C 3 N 4 and C 2 N), group-III (IV) monochalcogenides, boron nitride, and transition-metal dichalcogenides. [15][16][17][18] Due to their exceptional chemical and physical properties, as well as their great performances in a variety of applications, 2D materials have recently attracted widespread attention. 19,20 Furthermore, 2D structures have a large surface area to volume ratio, allowing the creation of additional photocatalytic reaction sites and low recombination rate of charge carriers, resulting in their migration to the surface.…”

Rational design of 2D/2D CS/SiC van der Waals type-II heterojunctions: a visible-light-driven photocatalyst for hydrogen production

“…A small η value can ensure the successful synthesis of CS/SiC vdWHs. 60 Different typical stacking configurations should be considered while constructing a vertical heterojunction from CS and SiC monolayers. Consequently, the phase structure of 2D materials determines their chemical and physical properties.…”

Strain-Modulated Photocatalytic Performance of Janus WSSe/g-GaN Heterostructures

“…Furthermore, Meng et al proved that 2D GaN/WS 2 and GaN/WSe 2 heterostructures are promising candidate materials for photocatalyst and photoelectronic applications . Opoku et al demonstrated that with the help of an electric field and biaxial strain, controllable structural and electronic properties could be realized in the g-GaN/Sc 2 CO 2 heterostructure . Ren et al proposed that in-plane strain can significantly enhance the photocatalytic performance of blue phosphorus and g-GaN heterostructures .…”
