Because of their desired features, including very specific surface areas and designable framework architecture together with their possibility to be functionalized, Metal Framework (MOF) is a promising platform for supporting varied materials in respect of catalytic applications in water treatment. In this work, a novel visible-light-responsive photocatalyst that comprised BiVO 4 together with MIL-125(Ti), was synthesized by a two-step hydrothermal approach. The characterization of as-obtained samples as performed by X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy, Fourier transform infrared spectroscope, X-ray photoelectron spectroscopy and ultraviolet-visible diffuse reflection spectra. Rhodamine B was selected being a target for the evaluation of the photocatalytic function of as-developed photocatalyst. The photocatalytic reaction parameters, for example, the content of BiVO 4 as well as initial concentration of Rhodamine B was researched. The composite photocatalyst possessing Bi:Ti molar ratio of 3:2 brought to light the fact that the greatest photocatalytic activity had the ability to degrade 92% of Rhodamine B in 180 min. In addition to that, the BiVO 4 /MIL-125(Ti) composite could keep its photocatalytic activity during the recycling test. The phenomenon of disintegration of the photogenerated charges in the BiVO 4 /MIL-125(Ti) composite was brought to discussion as well.

Semiconductor‐based photocatalysis is an environmental friendly and cost‐effective technique for water treatment. Due to their unique properties, metal–organic frameworks (MOFs) are considered as ideal platform to develop composite photocatalyst. In this study, Bismuth oxychloride (BiOCl) was first attempt to be incorporated with highly stable MOFs, UiO‐66(Zr) by hydrothermal reaction. Different characterization methods including X‐ray diffraction, Scanning electron microscopy, Fourier transform infrared spectroscope, X‐ray photoelectron spectroscopy had been used to prove the successful synthesis of composite photocatalyst. The resultant BiOCl/UiO‐66 composite showed higher photodegradation performance of Rhodamine B (RhB) under ultraviolet and visible light irradiation than that of pristine materials and their mechanically mixed sample. In addition, the composite exhibited good structural stability and reusability. The photocatalytic mechanism of RhB degradation over the composite under visible light proceeded via a photosensitization process. A better adsorptivity of RhB and effective electron transfer within the hybrid material might be responsible for the enhanced photocatalytic performance.

“…Guo et al constructed a Bi 2 MoO 6− x @Bi 2 MoO 6 core–shell structure, which not only promoted the solar light utilization and suppressed the charge recombination but also improved the surface reactivity, achieving excellent pollutant degradation performance . Meanwhile, various Bi 2 MoO 6 ‐based heterojunctions, such as Bi 2 MoO 6 /AgX (X = Cl, Br, I), Bi 2 MoO 6 /Ag 3 XO 4 (X = P, V), Bi 2 MoO 6 /CdS and Bi 2 MoO 6 /MOFs, etc. have been exploited, showing strong optical absorption and excellent photocatalytic activity.…”

Highly active photocatalysts driving chemical reactions are of paramount importance toward renewable energy substitutes and environmental protection. As a fascinating Aurivillius phase material, Bi 2 MoO 6 has been the hotspot in photocatalytic applications due to its visible light absorption, nontoxicity, low cost, and high chemical durability. However, pure Bi 2 MoO 6 suffers from low efficiency in separating photogenerated carriers, small surface area, and poor quantum yield, resulting in low photocatalytic activity. Various strategies, such as morphology control, doping/defect-introduction, metal deposition, semiconductor combination, and surface modification with conjugative π structures, have been systematically explored to improve the photocatalytic activity of Bi 2 MoO 6 . To accelerate further developments of Bi 2 MoO 6 in the field of photocatalysis, this comprehensive Review endeavors to summarize recent research progress for the construction of highly efficient Bi 2 MoO 6 -based photocatalysts. Furthermore, benefiting from the enhanced photo catalytic activity of Bi 2 MoO 6 -based materials, various photocatalytic applications including water splitting, pollutant removal, and disinfection of bacteria, were introduced and critically reviewed. Finally, the current challenges and prospects of Bi 2 MoO 6 are pointed out. This comprehensive Review is expected to consolidate the existing fundamental theories of photo catalysis and pave a novel avenue to rationally design highly efficient Bi 2 MoO 6 -based photocatalysts for environmental pollution control and green energy development.
