Effects of regulator ratio and guest molecule diffusion on VOCs adsorption by defective UiO-67: Experimental and theoretical insights

Facile preparation of graphitic carbon nitride nanosheet/agar composite hydrogels for removal of tetracycline via the synergy of adsorption and photocatalysis

“…26 In order to investigate the textural structures of the BCN and CNNS, nitrogen adsorption-desorption isotherms were measured and displayed. 27,28 As shown in Fig. 2b, both of these samples exhibited representative type IV isotherms with H 3 hysteresis loops, confirming the mesoporous features.…”

Adsorption and Degradation of Volatile Organic Compounds by Metal–Organic Frameworks (MOFs): A Review

“…These materials include activated carbon, porous silicon dioxide, aluminosilicate zeolites, carbon nanotubes, resins, molecular sieves, and columnar clays [9]. Zhao et al [10] performed experiments on the effect of the regulator ratio and guest molecule diffusion on the adsorption of VOCs by defective UiO-67 and showed a schematic representation of molecules entering the UiO-67 channel, as shown in Figure 2. In order to develop effective adsorbents for certain VOCs, modifications or functionalizations are typically applied to improve the specific properties of the base adsorbent.…”

Ternary photocatalysts based on MOF-derived TiO2 co-decorated with ZnIn2S4 nanosheets and CdS nanoparticles for effective visible light degradation of organic pollutants

“…22,23 Inspired by the fact that the positions of ZnIn 2 S 4 's energy bands are between those of TiO 2 and CdS, 24 constructing a ternary CdS/ZnIn 2 S 4 /TiO 2 heterostructure will help in the transfer of electrons from CdS to TiO 2 by a two-step process from the interface of CdS/ZnIn 2 S 4 to the interface of ZnIn 2 S 4 /TiO 2 , thus improving the charge separation efficiency, and this strategy is expected to be successfully applied to markedly enhance the photocatalytic properties of TiO 2 . In addition, it should be noted that metal–organic framework (MOF) materials have a wide range of potential applications in adsorption, 25 photocatalysis, 26 catalysis, 27,28 and other fields due to their unique performance advantages of controllable pore size, modified pore surface, low density, and high surface area. Moreover, our previous studies have verified that MOFs can be used as sacrificial templates to effectively control the morphologies and improve the specific surface area of TiO 2 , thus obtaining more active reaction sites for the photocatalytic reaction.…”
