“…The BET surface areas and pore size distribution of all samples including MIL-100(Fe) and CdS were measured by the nitrogen adsorption/desorption isotherms ( Figure 5 and Table 2 ). As mentioned in our previous report, after a calcination process, the BET surface area and pore volume of MIL-100(Fe) decreased significantly, which could be due to the decomposition of organic ligands from framework [ 23 ]. The porous F450 shows a large surface area 201 m 2 /g and pore volume (0.26 cm 3 /g).…”

“…The peaks located at ca. 24.1°, 33.2°, 35.6°, 40.8°, 49.5° and 54.1° could be indexed as (012), (104), (110), (113), (024) and (116) planes of α-Fe 2 O 3 (JCPDS 89–8103) [ 23 , 25 ]. Figure 1 b is the experimental XRD profile taken from as-deposited X–CdS/F450 hybrids.…”

“…The photocatalytic efficiency of bisphenol A removal over hierarchical 5-CdS/F450 is mainly enhanced by the following processes: (i) the porous structure of F450 creates multiple possible pathways for the migration of light-induced charges, facilitating the separation of photogenerated electron–hole pairs; (ii) the large surface area of porous F450 encourages the dispersal of CdS QDs, which may further improve the photocatalytic activity; (iii) the CdS coating significantly extends the visible light response of 5-CdS/F450, and hence, the formation of photon-generated carriers; and (iv) the typical type-II structure between F450 and CdS ensures that both the CB (−0.50 V vs. NHE at pH = 7.0) and VB (+1.78 V vs. NHE at pH = 7.0) edges of CdS are more negative than those of F450 (CB = +0.37 V and VB = +2.34 V vs. NHE at pH = 7.0) [ 20 , 23 , 38 , 39 ]. Accordingly, under visible-light irradiation, the photogenerated electrons excited from the CB of CdS tend to transfer to the CB of F450.…”

“…This is due to the originally structural characteristics of MOFs are retained to obtain pore structures. Our research group proposed the preparation of porous α-Fe 2 O 3 by pyrolyzation of an Fe-based MOF (MIL-100(Fe)) [ 23 ]. MIL-100(Fe) is a well-aligned porous precursor suitable for preparing porous α-Fe 2 O 3 ; therefore, it is a promising substrate for confining CdS into QDs.…”

In this work, CdS quantum dots (QDs) were planted on magnetically recyclable porous Fe2O3 (denoted as F450) to obtain CdS QDs/porous Fe2O3 hybrids (denoted as X–CdS/F450, in which X is the immersion times of CdS QDs). Porous Fe2O3 was first obtained by pyrolysis from an iron-containing metal–organic framework by a two-step calcination method. Next, CdS QDs (of average size 3.0 nm) were uniformly and closely attached to the porous F450 via a sequential chemical-bath deposition strategy. As expected, the X–CdS/F450 hybrids serve as high-performance photocatalysts for the degradation of bisphenol A, a typical endocrine-disrupting chemical. Almost ∼100% of the bisphenol A was degraded over 5-CdS/F450 after visible light irradiation for 30 min (λ ≥ 420 nm). In comparison, the degradation efficiency of pure F450 powder is 59.2%. The high performance of 5-CdS/F450 may be ascribable to the fast electron transport of porous F450, the intense visible-light absorption of the CdS QDs and the matched energy levels between CdS and F450. More significantly, through the photocatalytic degradation reaction, the X–CdS/F450 hybrids can easily be recovered magnetically and reused in subsequent cycles, indicating their stability and recyclability.

“…All of the samples exhibit the characteristic stretching vibrations of carboxylate groups in the range of 1700−1400 cm −1 . The peak at 746 cm −1 is ascribed to the C-H bending vibration of aromatic ring [35,36]. As for the peak at 545 cm −1 , it is related to Fe-O vibration [37].…”

Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due to their unique morphology, high photocatalytic performance, good chemical stability, easy synthesis, and low cost. In this review, the synthetic strategies of developing MOFs‐based photocatalysts are first introduced. Second, the recent progress in the fabrication of various types of MOFs composites photocatalysts is summarized. Third, the different applications including hydrogen evolution reaction, oxygen evolution reaction, overall water splitting, nitrogen reduction reaction, carbon dioxide reduction reaction as well as photodegradation of organic pollutants of MOFs‐based photocatalysts are summed up. Finally, the challenges and some suggestions for the future development of MOFs‐ and their composites‐based photocatalysts are also highlighted. It is expected that this report will help researchers to systematically devise and develop highly efficient photocatalysts based on MOFs and their composites.
