S-scheme MIL-101(Fe) octahedrons modified Bi2WO6 microspheres for photocatalytic decontamination of Cr(VI) and tetracycline hydrochloride: Synergistic insights, reaction pathways, and toxicity analysis

Development and study of a bifunctional photocatalyst based on SAPO-34 molecular sieve

“…6f. 7a that the BiVO 4 and SAPO-34 molecular sieves adsorbed less formaldehyde under dark conditions, 54 and again, the impregnation and grinding modification treatments did not change this. However, the synthetic modification could have a greater effect on the adsorption performance of the BiVO 4 @SAPO-34 molecular sieve catalysts, greatly enhancing the adsorption of formaldehyde molecules.…”

“…Fig.7a and bshow the degradation of aqueous formaldehyde solutions by the five catalysts under a mercury lamp atmosphere. It can be seen from Fig.7athat the BiVO 4 and SAPO-34 molecular sieves adsorbed less formaldehyde under dark conditions,54 and again, the impregnation and grinding modification treatments did not change this. However, the synthetic modification could have a greater effect on the adsorption performance of the BiVO 4 @SAPO-34 molecular…”

One-step solvothermal synthesis of the bimetallic Zr/Ce-UiO-67 metal–organic framework: a visible-light-activated photocatalyst for Cr(vi) detoxification

“…3 As an example of hybridizing MOFs with inorganic semiconductors, MIL-101(Fe)/ Bi 2 WO 6 has been used as an efficient photocatalyst owing to its affluent accessible active sites and great charge separation, which resulted in a high photocatalytic performance towards Cr(VI) elimination. 28 Moreover, several mixed metal MOFs, such as Fe/ In-NH 2 -MIL-88B, Ti/Zr-UiO-66, Zr/Ce-UiO-66, and Zr/Ce-UiO-67, are examples that have been reported for various photocatalytic applications. [29][30][31] The introduction of cerium into MOFs is a suitable choice, according to its low cost, and the facile conversion of Ce(VI)/ Ce(III) has attracted much attention in photocatalysis.…”

The Potential of Spent Coffee Grounds @ MOFs Composite Catalyst in Efficient Activation of PMS to Remove the Tetracycline Hydrochloride from an Aqueous Solution

“…Metal-organic frames (MOFs) have been widely used in the activation of PMS to remove organic pollutants [ 22 ]. Considering its large pore sizes and high specific areas [ 23 ], ample active centers, and plentiful derivatives [ 24 , 25 ], MOFs have garnered increasing interest in the catalytic field. Many scholars have prepared the MOFs materials, e.g., a core-heteroshell structural magnetic composite of ZIF-67/Vanadium-titanium magnetite (VTM) was synthesized through a solvothermal method, efficiently activating PMS for the removal of levofloxacin (LVF) (removal rate reaching 93.3%) [ 7 ].…”
