“…[92,111,126,127] MXenes can serve as an electron reservoir to promote the separation of charge carriers in many semiconductors, such as CdS, g-C 3 N 4 , Mo 2 S, TiO 2 , Zn 2 In 2 S 5 , ZnIn 2 S 4 , BiOBr, and Ag 3 PO 4 (Table 3). [85,87,90,94,105,115,128] The DFT calculation on a typical TiO 2 photocatalyst shows that the jΔG H Ã j of intermediated state H* is 0.00283 eV when using O-terminated Ti 3 C 2 MXene as the cocatalysts, much lower than that of those frequently used cocatalysts in water splitting reactions, such as Pt (0.09 eV), MoS 2 (0.08 eV), and WS 2 (0.22 eV). [98] Therefore, MXenes could be better cocatalysts from an energy point of view.…”

“…The decrease in H 2 rate with excessive Ti 3 C 2 loading of above 25% may be due to developing charge recombination centers, thus the photocatalytic activity decreased. Previously, a MoS 2 /Ti 3 C 2 composite was investigated and 30% Ti 3 C 2 was observed to be as the optimized loading amount to increase H 2 yield, which is 2.3 times higher than what was produced over pure MoS 2 . In another development, 1D CdS nanorods coupled with 2D Ti 3 C 2 MXene nanosheets were obtained to provide an accelerated separation of charge carriers .…”

“…Zhang et al 50 prepared MoS 2 /Ti 3 C 2 catalysts with unique spherical/flake structure by hydrothermal method. The maximum hydrogen production of 30% Ti 3 C 2 loaded MoS 2 /Ti 3 C 2 heterostructure was 6144.7 mmol g -1 h -1 , which was 2.3 times that of pure MoS 2 .…”
