Highly intra- and inter-plane crystalline ReS /g-C3N4: Facile synthesis and boosted photocatalytic H2 evolution

Charge self-regulation of Ti sites in Ti3C2 MXene via rich unsaturated Ti for boosted photocatalytic hydrogen generation

“…8(A) and (B), the positions of the Fermi levels of TiO 2 and Ti 3 C 2 F x - U can be easily estimated to be −3.97 and −1.47 eV, respectively, which contributes to the spontaneous migration of free electrons from Ti 3 C 2 F x - U to TiO 2 particles in the Ti 3 C 2 F x - U /TiO 2 photocatalyst. 55,56 Owing to the spontaneous transfer of free electrons from Ti 3 C 2 F x - U to TiO 2 under dark conditions, a built-in electric field was derived at their contacted interface pointing from Ti 3 C 2 F x - U to TiO 2 (Fig. 8(C) and (D)), which can further promote the photoinduced-electron migration from TiO 2 to Ti 3 C 2 F x - U during photocatalytic H 2 evolution.…”

Dual built-in spontaneous electric fields in an S-scheme heterojunction for enhanced photocatalytic H2O2 production

“…After 15 minutes, 2 mL of reaction suspension was extracted to detect the produced H 2 O 2 via employing a UV-1240 spectrophotometer (Shimadzu, Japan), based on the colorimetric method at the wavelength of 385 nm. 30–32 Finally, a standard H 2 O 2 -concentration curve and absorbance (Fig. S7†) were used to precisely obtain the actual concentration of the produced H 2 O 2 .…”
