“…The as-prepared MOF-based binary composites for the photocatalytic removal of environmental pollutants are summarized in Table 5. Except for MIL-53(Fe) with 1D lozenge-shaped channels and ultra-small surface area (<100 m 2 g −1 ), [165][166][167] the coupling of other MOFs with a photoactive semiconductor led to a decreased surface area relative to pristine MOFs. Due to the comprehensive effects of various factors, including light absorption, charge generation, separation and transfer properties, the photocatalytic performance for environmental remediation can be increased.…”

“…27C). 165,167 For example, an Ag 3 PO 4 /MIL-53(Fe) composite was prepared through a simple in situ precipitation strategy. The as-prepared binary composite displayed enhanced photocatalytic performance for the degradation of multiple antibiotics such as tetracycline (TC), oxytetracycline (OTC), chlortetracycline (CTC) and deoxytetracycline (DCL).…”

“…During photocatalysis, a series of oxygen species including singlet oxygen ( 1 O 2 ), superoxide radical ( • O 2 À ), and hydroxyl radical ( • OH) with high oxidizing ability were formed from the photoinduced electrons/holes to degrade various organic pollution. [42,142,196,238,239] In addition, photogenerated holes could also directly participate in the oxidative degradation process. [39] However, different from the photocatalysis organic transformation, • OH radicals as the most oxidative species were commonly applied in the degradation of pollutants.…”

Metal−organic frameworks (MOFs) are a new class of porous, crystalline materials with promising applications in the fields of energy and environment. Postsynthetic modification (PSM) approaches are shown to be powerful techniques to introduce new functionalities to parent frameworks. PSM methods to functionalize MOFs can be divided into four main categories based on their unique structures: covalent modification, coordinative transformation, encapsulation, and hybridization with other compounds. These approaches are proven to be an important tool for increasing structural stability and introducing desired properties, which expand the applications of MOFs. This review focuses on the current advancements of four PSM methods to construct functionalized MOFs for photocatalytic applications in water splitting, CO2 reduction, organic transformation, and degradation of water pollutants. The challenge and perspectives on PSM of MOFs for photocatalysis are also discussed.

The development of an efficient and environment-friendly photocatalyst for antibiotics degradation is of great significance and still remains a major challenge. Herein, a novel Sillén-Aurivillius layered oxide Bi7Fe2Ti2O17Cl is successfully synthesized via a one-step flux route (noted as F-BFTOC) and solid-state reaction (noted as S-BFTOC). The as-prepared F-BFTOC manifests the enhanced visible-light photocatalytic performance towards tetracycline (TC) degradation compared with Bi4NbO8Cl and its degradation efficiency reaches 90% within 90 min. Additionally, the proposed degradation pathway and photocatalytic mechanism are systematically investigated by liquid chromatography tandem-mass spectrometry (HPLC-MS), active species trapping test, electron spin resonance (ESR) and first-principles calculations. The superior degradation of antibiotics is primarily derived from the photo-generated h+, and radical ·O2− as the dominant active species. More importantly, the F-BFTOC exhibits excellent cycle stability and TC is ultimately transformed into non-toxic open-loop products. Simultaneously, Rhodamine B (RhB) as a typical organic pollutant is further employed to evaluate the photocatalytic activity of F-BFTOC, and 98% of the degradation efficiency is achieved. BFTOC as a multifunctional photocatalyst for pollutant degradation offers a new insight for Sillén-Aurivillius photocatalytic in the field of water purification.
