Near-infrared light induced adsorption–desorption cycle for VOC recovery by integration of metal–organic frameworks with graphene oxide nanosheets

Abstract

Metal-organic frameworks are appealing candidates for adsorption of VOCs from contaminated air due to their outstanding capturing capacities, but the traditional regeneration methods of used MOFs adsorbents often suffer from...

Boosting the ultraviolet shielding and thermal retardancy properties of unsaturated polyester resin by employing electrochemically exfoliated e-GO nanosheets

“…After the UV absorption process, the e-GO nanosheets dissipated UV radiation via converting the absorbed radiation energy into heat to prevent the damaging UV-rays. 71 (2) Another mechanism for UV-resistance of UPR/e-GO nanocomposites is the role of e-GO nanosheets in scattering the UV rays. 72 The e-GO nanosheets can reflect UV-rays because of the unique planar 2D structure.…”

Progress and Perspectives on Promising Covalent‐Organic Frameworks (COFs) Materials for Energy Storage Capacity

“…Due to the sustainable and infinite energy of visible light from the solar system, researchers have favored increasing the innervation wavelength of light-response COFs towards extended zones. [79,80] For COFs to remain stable when exposed to UV light, organic linkers are required. Large molecules in organic linkers based on p-systems paired with diverse benzene rings can improve emission conflict due to the considerable energy delocalization of p-structures.…”

“…The reaction in aqueous solutions is complicated by the fact that most COF compounds are unstable when exposed to UV light. Due to the sustainable and infinite energy of visible light from the solar system, researchers have favored increasing the innervation wavelength of light‐response COFs towards extended zones [79,80] . For COFs to remain stable when exposed to UV light, organic linkers are required.…”

Dual regulation of hierarchical porosity and heterogeneous interfaces in Cu-BTC/Bi2MoO6 for thermally-driven and UV-light-activated selective acetone sensing

“…Recent years have witnessed the outstanding discovery of semiconductor-like properties and excellent UV-light utilization performance of specic MOFs, thereby presenting their promising application prospects in photoactivated gas sensing. [9][10][11] Nevertheless, monomeric MOF materials are subject to low electrical conductivity, structural instability, and limited surface active sites, ultimately leading to unsatisfactory gas sensing activity, thus posing signicant challenges that demand more efficient ways to overcome these issues. 12,13 The pre-designable modication of monomer MOF crystals through a coordination defect-induced strategy offers a promising avenue for advancing MOFbased sensors with high gas permeability and adjustable sensing properties.…”
