Highly Strained Bi‐MOF on Bismuth Oxyhalide Support with Tailored Intermediate Adsorption/Desorption Capability for Robust CO2 Photoreduction

“…The structure of Bi-MOF in this work is shown as the inset in Figure 1a, with typical four kinds of channels for mass transfer. [27,28] The simulated XRD pattern from the structure could match well with the recorded XRD pattern of the asprepared Bi-MOF (Figure 1a). XRD pattern of BiOBr reveals the tetragonal phase of BiOBr NSs (JCPDS:09-0393) with existence of a small portion of Bi 4 O 5 Br 2 owing to the high temperature under hydrothermal process as disclosed in previous literature (Figure 1b).…”

“…From FT-IR spectra, the two typical peaks at 1400-1614 cm À 1 assigned to the characteristic bands of aromatic carbons and at 765 cm À 1 assigned to Bi-O stretching vibration in Bi-MOF could be well matched (Figure 1c). [27] From O 1s high revolution spectra, the appearance of the O in ligands and O in Bismuth-oxo clusters of Bi-MOF also demonstrates the successful growth of surfacemounted Bi-MOF, which is further confirmed by the appearance of the C=O from the C1s spectra and the elemental analysis (Figure 1c, d, Figure S3 and Table S1). In the more sensitive Raman characterization, both the vibrational bands of Bi-O in Bi-MOF and Bi-Br in BiOBr could be obviously observed and distinguished (Figure 1e).…”

Double-Solvent-Induced Derivatization of Bi-MOF to Vacancy-Rich Bi4O5Br2: Toward Efficient Photocatalytic Degradation of Ciprofloxacin in Water and HCHO Gas

“…Fourier transform infrared (FTIR) spectra (Figure b) of BOB, CAU-17, MBO-H, MBO-0, and MBO- x shows that the O–H stretching vibration of adsorbed H 2 O on the photocatalyst produces broad peaks in all spectra in the band around 3445 cm –1 . The peak at 760 cm –1 in CAU-17 and MBO-0 is the stretching vibration of the O–Bi–O group . The absorption at 527 and 1397 cm –1 in the MBO- x spectra is mainly related to the stretching vibration of the Bi–O and Bi–Br bond in Bi 4 O 5 Br 2 .…”

In Situ Implantation of Bi2S3 Nanorods into Porous Quasi-Bi-MOF Architectures: Enabling Synergistic Dissociation of Borohydride for an Efficient and Fast Catalytic Reduction of 4-Nitrophenol

“…As shown in Figure S2, the parent Bi-MOF presents a typical hexagonal prism-shaped nanorod structure with a diameter of 600−900 nm and a length of about 3−5 μm, which matches the intrinsic structure of Bi-based CAU-17 MOF. 45,46 The corresponding energy-dispersive spectroscopy (EDS, Figure S3, Supporting Information) clearly illustrates the homogeneous distribution of Bi, O, and C elements in Bi-MOF. Figure 3a shows a general SEM image of Bi 2 S 3 @quasi-Bi-MOF derived from Bi-MOF, which suggests that the sample obtained via localized sulfidation strategy maintains the welldefined hexagonal prisms.…”
