Characterization of Type I/II g-C3N4/MoS2 van der Waals Heterostructures: A New Theoretical Insight

“…The vertical separation (d) between the g-C 3 N 4 layer and MoS 2 layer is calculated at ca. 2.93 Å, which is the archetypal vdW equilibrium spacing. , The current results are in line with previous conclusions. , …”

“…2.93 Å, which is the archetypal vdW equilibrium spacing. 34,35 The current results are in line with previous conclusions. 15,17 According to the alignment of aperture in the g-C 3 N 4 and MoS 2 units, four stacking modes are considered, as shown in Figure 3.…”

Enhancing solar-to-hydrogen efficiency with an S-scheme GaTe/PtS2 van der Waals heterojunction with high light absorption

“…Fig. 8(d) demonstrates that the STH efficiency of GaTe/PtS 2 is superior to those of other heterojunction photocatalysts such as PtS 2 /As (44.86%), 38 PtS 2 /g-C 3 N 4 (31.64%), 37 g-C 6 N 6 /InP (27.32%), 56 GaN/InS (26.33%), 57 and SeGe/SnS (26.45%). 58 The GaTe/PtS 2 heterojunction satisfies the essential prerequisites for efficient photocatalytic water splitting, thus allowing better utilization of sunlight.…”

“…36 Additionally, recent studies have focused on constructing heterojunctions using PtS 2 for photocatalysis, such as PtS 2 /g-C 3 N 4 , PtS2/As, PtS 2 /CdO, PtS 2 / GaSe, and PtS 2 /BN. 16,[37][38][39][40] Hence, the considerable potential of PtS 2 as a photocatalyst for water splitting is reasonable to believe.…”

Effective modulation of the exotic properties of two-dimensional multifunctional TM2@g-C4N3 monolayers via transition metal permutation and biaxial strain

“…5 As a derivative of 2D materials, C x N y -based heterostructures are combined by van der Waals forces between the C x N y layer and other 2D layers. Based on the double-layer structure characteristics of this interlayer-coupled van der Waals heterostructure, it can effectively separate positive and negative charges and hinder the recombination of charges, thereby enhancing the catalytic performance of water splitting 11,12 and expanding its application in optoelectronic devices such as light-emitting diodes (LEDs), photodetectors, light sensors, light transistors, and solar cells. [13][14][15] Among these diverse nitrogen carbide monolayers, because of its great visible light response and excellent thermal and chemical stability, g-C 3 N 4 has been extensively applied in photocatalytic water splitting, reduction of CO 2 and NO x , and organic pollutant degradation.…”
