Liquid exfoliation of g-C3N4 nanosheets to construct 2D-2D MoS2/g-C3N4 photocatalyst for enhanced photocatalytic H2 production activity

2D/2D heterostructured photocatalyst: Rational design for energy and environmental applications

“…The photocatalytic H 2 evolution performance of 2D layered niobate oxides (e.g., SnNb 2 O 6 ) can also be improved by coupling 2D MoS 2 nanosheets [70]. More recently, Yuan's group [82] further employed 2D MoS 2 nanosheets to combine with 2D metal-free semiconductors to form BP/MoS 2 and g-C 3 N 4 /MoS 2 [81] 2D/2D composites. In the BP/MoS 2 2D/2D photocatalyst system, the MoS 2 acts as both an electron sink and a cocatalyst which will greatly reduce the recombination of electron-hole pairs, while the 2D/2D smart structure provides large 2D nanointerfaces for photogenerated charge transfer, and thus synergistically promotes the H 2 evolution rate (Fig.…”

A Mini Review of the Preparation and Photocatalytic Properties of Two-Dimensional Materials

“…In order to satisfy the above conditions, the preparation of effective photocatalytic water splitting catalysts by reducing the dimension of materials has attracted much attention from the research field. In the study of 2D semiconductor materials, these three directions are all conducive to improving the efficiency of semiconductor induced light reaction of 2D materials, extending the wavelength of the excitation reaction, reducing the recombination between carriers and increasing the active sites around the surface (Dong et al, 2019;Sun et al, 2019;Yuan et al, 2019), as shown in Figures 2a-f.…”

“…Meanwhile, the above study laid a foundation for the photocatalytic application of 2D composites. The effect of MoS 2 amount on the photocatalytic H 2 evolution performance, (Yuan et al, 2019). Copyright 2019, Elsevier.…”

Two-dimensional ultrathin MoS2-modified black Ti3+–TiO2 nanotubes for enhanced photocatalytic water splitting hydrogen production

“…Adhikari et al prepared Z-scheme MoS 2 -modified Ag 2 Mo 2 O 7 with excellent catalytic activity [49] . Yuan et al prepared MoS 2 /g-C 3 N 4 photocatalysts with remarkable photocatalytic HER activity [50] . Moreover, because of the presence of the Mo-S bond, MoS 2 can be easily transformed into 2D ultrathin lamellae, which increases its specific surface area and the number of edge S atoms, thereby, increasing the number of HER active sites and shortening the electron transferring route to improve the charge carrier separation [51][52][53] .…”
