A hierarchical Bi-MOF-derived BiOBr/Mn0.2Cd0.8S S-scheme for visible-light-driven photocatalytic CO2 reduction

Toward Tailoring Metal–Organic Frameworks for Photocatalytic Reduction of CO2 to Fuels

“…Different from the above Z-scheme heterojunction, the S-scheme heterojunction constructed by MOF-BiOBr/Mn 0.2 Cd 0.8 S is mainly driven by coulomb interaction and internal electric field, and the accumulated electrons in the BiOBr conduction band will recombine with the holes in the MCS valence band. Thereby, this S-scheme heterojunction eliminates relatively ineffective electrons and holes in BiOBr and MCS, further inhibiting charge recombination (Figure c) . Besides, the S-scheme heterojunction constructed by CoNi-MOF and TiO 2 can prolong the lifetime of photogenerated carriers.…”

“…Thereby, this S-scheme heterojunction eliminates relatively ineffective electrons and holes in BiOBr and MCS, further inhibiting charge recombination (Figure 9c). 145 Besides, the S-scheme heterojunction constructed by CoNi-MOF and TiO prolong the lifetime of photogenerated carriers. The average lifetime of TiO 2 @CoNi-MOF (15.4 ns) is greater than that of TiO 2 (11.7 ns) and CoNi-MOF (9.0 ns).…”

Bimetallic UiO-66-NH2(Zr–Hf) synergistic photocatalytic and piezoelectric effects for the degradation of rhodamine B

“…5 At present, they have been broadly applied to hydrogen production, 6 visible light nitrogen fixation, 7 and CO 2 reduction. 8 Among several MOFs, UiO-66 is of interest for its outstanding hydrothermal and chemical stability. UiO-66-NH 2 obtained by modifying the ligand has a relatively narrower band gap, which is conducive to broadening the spectral response range.…”

Bi2O2CO3 Nanosheet Composites with Bi-Based Metal–Organic Frameworks for Photocatalytic H2O2 Production

“…22 In recent years, Bi-MOFs, as a variety of MOFs with relatively novel functions, have been widely used in photocatalytic degradation of organic pollutants and carbon sequestration. 23,24 Previous reports have found that Bi-MOF contains holes with a diameter of 3.4−3.5 Å and is a 3D porous framework, which gives it excellent adsorption capacity for reactants. 25 What's more, Bi 3+ in the metal−organic frameworks has a larger overpotential, which will accelerate the production of H 2 O 2 due to the suppression of hydrogen evolution.…”

“…Assuredly, the construction of MOFs (metal–organic frameworks) and inorganic hybrid heterojunctions is a promising strategy to achieve efficient charge separation and enhance photocatalytic performance. , Due to their high surface area, specific surface functionalities, and excellent gas adsorption capacity, MOFs can be considered promising photocatalysts in realizing efficient H 2 O 2 production .
