Unravelling the interfacial charge migration pathway at atomic level in 2D/2D interfacial Schottky heterojunction for visible-light-driven molecular oxygen activation

Fabrication of a high-efficiency CdS@TiO2@C/Ti3C2 composite photocatalyst for the degradation of TC-HCl under visible light

“…The positive slopes of the Mott-Schottky plots indicate that both the TiO 2 @C/ Ti 3 C 2 and CdS samples are n-type semiconductors. 49,50 The flat band potentials of TiO 2 @C/Ti 3 C 2 and CdS are specified to be À0.40 and À0.55 eV vs. Ag/AgCl, respectively, which correspond to À0.20 and À0.35 eV vs. NHE. It is worth noting that the CB potential of an n-type semiconductor is 0.1 eV above the flat band level.…”

Iodine doped Z-scheme Bi2O2CO3/Bi2WO6 photocatalysts: Facile synthesis, efficient visible light photocatalysis, and photocatalytic mechanism

“…Moreover, The EIS Nyquist plot of S5 exhibited the smallest radius compared with S1 and S8 (Fig. 7b), which implied that S5 exhibited remarkable improvement in inhibiting the charge recombination [57]. Furthermore, the PL, photocurrent and EIS results show the S5 has high photogenerated electrons and holes separation.…”

Positioning MXenes in the Photocatalysis Landscape: Competitiveness, Challenges, and Future Perspectives

“…In addition, different MXenes-based composites have also been fabricated through in situ growth of semiconductors on the 2D surface of MXenes, such as Ti 3 C 2 T x -CdS, [70,71] Ti 3 C 2 T x -ZnS, [72] [73] Ti 3 C 2 T x -ZnIn 2 S 4 , [74] Ti 3 C 2 T x -BiOBr, [75] Ti 3 C 2 T x -BiOCl, [76] [77] Nb 2 CT x -TiO 2 , [34] Nb 2 CT x -Bi 2 WO 6 , [78] Mo 2 CT x -CdS, [79] etc. [80][81][82][83][84][85][86] (detailed information can be found in Table 1). Notably, the surface of MXenes features with functional groups as well as high-portion exposed transition metal atoms.…”
