Bifunctional honeycomb hierarchical structured 3D/3D ReS2/ZnIn2S4-Sv heterojunction for efficient photocatalytic H2-evolution integrated with biomass oxidation

Construction of a Bi2WO6/BiVO4 photocatalytic system for efficient visible light degradation of tetracycline drugs

“…The light absorption range of 10% W/BVO is not much different from that of BiVO 4 , indicating that a small amount of Bi 2 WO 6 does not affect the light absorption ability of BiVO 4 . The band gap energy of the semiconductor was calculated by Kubelka–Munk function (eqn S(2)†), and the energy band position of the semiconductor was calculated by eqn S(3) and S(4) † 49,50 . The results are shown in Fig.…”

Photocatalytic Applications of ReS2-Based Heterostructures

“…In a type-I heterostructure (shown in Figure 3 a), the photo-excited electrons and holes in the wide-gap material transfer to the narrow-gap material (ReS 2 ), as demonstrated by the arrows [ 46 , 50 , 51 , 53 , 54 , 91 , 92 , 93 ]. The quantum confinement of the accumulated electrons and holes in the same semiconductor facilitates high carrier recombination rate and radiative recombination, which is incredibly detrimental to photocatalytic activity but desirable in light-emitting applications [ 91 , 94 ].…”

“…The quantum confinement of the accumulated electrons and holes in the same semiconductor facilitates high carrier recombination rate and radiative recombination, which is incredibly detrimental to photocatalytic activity but desirable in light-emitting applications [ 91 , 94 ]. To inhibit recombination of photo-generated charge, a cocatalyst such as Pt that is deposited in situ onto the surface [ 54 ] or abundant sulfur vacancies [ 93 ] can act as an electron trapper to facilitate electron accumulation and transfer. Additionally, the abundant edge reaction sites in ultrathin ReS 2 nanosheets in the composites can also accumulate electrons, thus accelerating reaction kinetics of the hydrogen evolution [ 53 ].…”

Facile synthesis of water-soluble silver nanoclusters for the photocatalytic degradation of dyes by multivariate optimization approach

“…Rhodamine B has been treated with different nanocomposites in a range of studies, such as Ag/FWO/GCN and Ag/ Fe 3 O 4 nanocomposites. 37,38 Highly uorescent metal nanoclusters have great potential to be used as photocatalysts for dye degradation. In this juncture, uorescent NCs are of particular interest.…”
