Bifunctional S-scheme g-C3N4/Bi/BiVO4 hybrid photocatalysts toward artificial carbon cycling

A novel step-scheme BiVO4/Ag3VO4 photocatalyst for enhanced photocatalytic degradation activity under visible light irradiation

“…and (121) crystal planes of BiVO4 increased[59], while the intensities of the diffraction peaks corresponding to the (121) and (1-21) planes of Ag3VO4 decreased. This indicates that BiVO4 compounded well with Ag3VO4.…”

Construction of LSPR-enhanced 0D/2D CdS/MoO3− S-scheme heterojunctions for visible-light-driven photocatalytic H2 evolution

“…The advantage of Z-scheme and S-scheme heterostructures over traditional type-II heterostructures is that the photoexcited electrons preserved at higher reduction potentials would take part in water-splitting reactions, which is beneficial for achieving higher photocatalytic reaction efficiency [29][30][31][32]. It is worth mentioning that the migration distance between the electrons and holes can be further shortened in the S-scheme due to band bending caused by the internal electric field of the semiconductors, leading to faster separation of the photo-induced carriers in comparison to the Z-scheme [33]. The first S-scheme heterojunction, 2D/2D WO3/g-C3N4, was published by Yu et al [34], and it has been suggested that the construction of S-scheme heterojunctions relies on the band offset of the two semiconductors.…”

Structural engineering of 3D hierarchical Cd0.8Zn0.2S for selective photocatalytic CO2 reduction

“…The solar-driven reduction of CO2 is a promising strategy for obtaining value-added chemicals given the rapid consumption of global energy and expansion of the global warming crisis [1][2][3][4]. To date, diverse light-absorbing photocatalysts known for their favorable photochemical and electrical properties have been widely developed as valuable materials to reduce CO2 to CO or hydrocarbons [5][6][7]. However, owing to the inert scaling properties of CO2, the reduction is frequently restricted by the strong chemical bonding and inactive carrier excitation, hugely limiting the practical applications of CO2 reduction [8,9].…”
