Photoelectroactive metal–organic frameworks

“…Photodegradation of rhodamine B (RhB) (Scheme 4) is one of the major concerns in wastewater treatment. 72,107,[181][182][183][184][185][186] . 182 The photodegradation of methylene blue (MB) (Scheme 4) is another concern in wastewater treatment.…”

“…Meanwhile, the aforementioned multifunctional MOFs 107,183,185 were also reported to photodegrade the MV dye under UV light irradiation involving the generation of active species of cOH radicals.…”

“…Crystal violet (CV) and basic red 2 were photodegraded by a hybrid Cd MOF that was constructed from CdI 195 In addition, MOF-based photocatalysts were also reported to degrade organic dyes like metanil yellow (MY), methyl orange (MO), direct red 23, basic blue 41, malachite green (MG), Congo red (CR), and AB 92 under visible light irradiation. 72,185,190,192,196 3.5.2 Photodegradation of antibiotics. Antibiotics represent another threat in contaminated water although originally used for humans and animals as medical treatments.…”

“…Photodegradation of rhodamine B (RhB) (Scheme 4) is one of the major concerns in wastewater treatment. 72,107,181–186 For instance, a pristine MOF {[Cu(tpt)]·3H 2 O·0.5SO 4 } n constructed from CuSO 4 ·5H 2 O and 2,4,6-tris(4-pyridyl)-1,3,5-triazine (tpt) demonstrated aqueous RhB (20.0 mg L −1 ) degradation in the presence of 30% H 2 O 2 at room temperature under visible light LED irradiation, with a degradation efficiency of 77% and a rate constant of 2.10 × 10 −2 min −1 within 70 min involving the generation of active species of ˙OH. 72 In another case, SNNU-110 constructed from In(NO 3 ) 3 · x H 2 O and 4,4′,4′′- s -triazine-1,3,5-triyltri- p -aminobenzoic acid showed a degradation efficiency of 94.6% for aqueous sulforhodamine B within 70 min at ambient temperature under xenon lamp irradiation.…”

“…73,193 Methyl violet dye in aqueous solution (10 mg L −1 ) was photodegraded with rate constants of 1.798 × 10 −2 min −1 (by Co MOF) and 2.003 × 10 −2 min −1 (by Zn MOF) within 40 min under UV light (365 nm) irradiation, which involved the generation of active species of ˙O 2 − radicals. Meanwhile, the aforementioned multifunctional MOFs 107,183,185 were also reported to photodegrade the MV dye under UV light irradiation involving the generation of active species of ˙OH radicals.…”
