Efficient removal of organic pollution via photocatalytic degradation over a TiO2@HKUST-1 yolk-shell nanoreactor

Recent advances in Cu-BTC MOF-based engineered materials for the photocatalytic treatment of pharmaceutical wastewater towards environmental remediation

“…Qiao et al proposed a unique yolk–shell nanoreactor based on TiO 2 @HKUST-1 with noticeably higher stability and photocatalytic efficacy for the elimination of TC under visible light. 24 The degradation efficiency of the TiO 2 @HKUST-1 was found to be 92.40% within 60 min, which was significantly higher than its pristine counterparts. The designed nanoreactor structure effectively enhanced the interfacial contact that significantly led to the increase in specified surface area, carrier density and separation of photogenerated e − and h + , thereby increasing the photocatalytic efficiency.…”

“…The solvothermal approach is the most extensively employed method for synthesizing Cu-BTC MOF in a liquid phase. This involves the continuous stirring of H 3 BTC in a mixed solvent of BnOH : ethanol (15 : 1) and metal ions maintained at a predetermined temperature of 80 °C for 3 h. 24,25 The subsequent filtration of the reaction mixture, along with solvent evaporation, finally yields pure MOF crystals. Qiao et al proposed a yolk–shell nanoreactor based on TiO 2 @HKUST-1 by applying a three-step synthetic route, 24 as demonstrated in Fig.…”

“…To ensure complete contact of the pollutant molecule with TiO 2 , the HKUST-1 shell adsorbs the molecule to the TiO 2 @HKUST-1 cage. 24,26 This transfer of charges efficiently increases photocatalytic performance by successfully limiting the rate of recombination of the charge carriers.…”

Multifunctional Luminescent 3D Ln-MOFs with High Sensitivity for Trace Detection of Micronutrients

“…Metal–organic frameworks (MOFs) are novel porous crystalline compounds that are created by combining ligands that are organic in nature with many teeth to coordinate metal ions or clusters. MOFs materials have large surface area, porous properties and high crystallinity, with regular arrangement and dense adsorption active sites inside the pores. , The simultaneous luminescence of lanthanide ions (Ln 3+ ) and ligands produces double fluorescence emission, which reduces the interference of external conditions on detection, thus improving the detection sensitivity and reducing the detection limit, which makes the fluorescence MOFs get great development. − …”

Synthesis of Chrysanthemum‐Like BiOBr Microspheres by Structure Induction of Chitosan for Enhancing Photocatalytic Activity

“…Zhao et al used a one-step hydrothermal method to synthesize Bi 2 O 2.33 /Bi 2 O 3 @ECNF with excellent adsorption and photocatalytic performance for anionic pollutants and easy recycling of organic pollutants after removal with good cyclic stability. [3] A TiO 2 @HKUST-1 nanoreactor with an egg yolk shell structure was synthesized by in situ growth and hydrothermal method by Qiao et al [4] Its unique structure and enhanced adsorption properties led to the enrichment of RhB and TC molecules on the surface and cavity of the yolk-shell nanoreactor. The composite structure can effectively separate photogenerated electron holes and further improve the photocatalytic efficiency.…”
