In-situ construction of Bi/defective Bi4NbO8Cl for non-noble metal based Mott-Schottky photocatalysts towards organic pollutants removal

Boosting Light‐Driven Photocatalytic Water Splitting of Bi4NbO8Br by Polarization Field

“…Furthermore, the binding energy of BNB is shifted in the XPS spectrum of Bi, O, Br, which also shows that the incorporation of Nb element changes the electronic structure of the material and reduces the binding energy than BOB (Figure S1, Supporting Information). [16] All the above results demonstrate the intercalation of the NbO 6 octahedron in BOB, forming a new layered material BNB. The morphologies of BNB and BOB nanosheets were characterized by scanning electron microscopy (SEM).…”

Z-Scheme Heterojunction of 3-Dimensional Hierarchical Bi3O4Cl/Bi5O7I for a Significant Enhancement in the Photocatalytic Degradation of Organic Pollutants (RhB and BPA)

“…Although various semiconducting photocatalysts with high photocatalytic performance have been reported, there are still some limitations, such as high electron–hole recombination, inappropriate redox potentials, and low capability of visible-light absorption [ 9 ]. In particular, to enhance the separation and transport of photo-excited charge carriers, which is a key process during the photocatalytic process, various strategies have been explored including nonmetal doping [ 10 ], the deposition of noble or non-noble metal as a cocatalyst on the semiconducting photocatalyst [ 11 , 12 , 13 , 14 ], type-II heterojunction [ 15 ], and Z-scheme heterojunction photocatalyst [ 16 ] through the coupling of two semiconducting materials.…”

Modulating Photon Harvesting Through Constructing Oxygen Vacancies‐Rich 0D/2D Plasmonic Bi/Bismuth Oxybromide Upconversion Nanosheets Toward Improved Solar Photocatalysis

“…Generally, oxygen vacancies (OVs) are produced by coupling with the formation of Bi species, especially in ultrathin 2D Bi-based materials. [13,42] Moreover, OVs could not only enhance the light-harvesting ability by introducing intermediate energy levels in the bandgap, but also acted as charge carrier traps to promote the separation and transfer of the e À /h þ pairs. [43] Nevertheless, the excessive OVs can also act as the recombination sites for photocarriers, which deteriorates the photocatalytic performance.…”
