Z-Scheme Ag3PO4/g-C3N4 Nanocomposites for Robust Cocatalyst-Free Photocatalytic H2 Evolution Under Visible Light Irradiation

Boosting interlayer charge transfer in polymeric carbon nitride by Mo ions for efficient photocatalytic H2 evolution

“…4(d). 50 Compared with CN, 3Mo–CN has the CD position still more negative than the H + /H 2 potential, and the VB position more positive than O 2 /H 2 O potential.…”

Photoelectrochemical Water Splitting: A Visible-Light-Driven CoTiO3@g-C3N4-Based Photoanode Interface Follows the Type II Heterojunction Scheme

“…As a result, the generation of hybrid energy states for CTOCN nanohybrids is firmly proven by UV-DRS spectra, Mott–Scottky analysis, and UPS analysis. Thereby, Figure g displays the corresponding energy level diagram with respect to V FB vs Ag/AgCl from Mott–Schottky plots and V B from UPS. , …”

“…The band bending effect might be nullified by raising the applied voltage, which is how g-CN’s CB (−1.12 eV) became more negative than CTO’s (−0.48 eV). When compared to CTO’s VB (+1.59 eV), g-CN’s is more positive, i.e., possessing greater energy. − Since the CB of g-CN and the VB of CTO have different energy levels, photogenerated electrons and holes move freely between the two. As a result, the type II heterostructured materials developed solid bonds with one another.…”

FeV3O8/MoS2 nanostructure heterojunctions as a highly effective electrocatalyst for hydrogen evolution

“…In a word, the smaller the arc radius is, the faster the electron transfer would be. 54,55 All FeV 3 O 8 /MoS 2 heterostructures show a smaller arc radius because the electronic resistance decreases and the conductivity increases after FeV 3 O 8 is compounded with pure MoS 2 . Notably, the arc radius for FVO 40 -MS is the lowest, which possesses the highest efficiency of the charge separation.…”
