Recyclable Cu(i)/ZrSBA-15 prepared via a mild vapor-reduction method for efficient thiophene removal from modeled oil

Abstract

Recyclable Cu(i)/ZrSBA-15 composites prepared via a controllable and effective methanol vapor-reduction method exhibited excellent adsorption capacity for the removal of thiophene (29.9 mg g−1).

Cuprous/Vanadium Sites on MIL-101 for Selective CO Adsorption from Gas Mixtures with Superior Stability

“…Contributing to this distinction in the bond strength, CO can be readily separated from gas mixtures. , It is known that the efficiency of the π-complexation adsorption is mainly dependent on the structural property of adsorbents. , With regard to the fabrication of Cu­(I) π-complexation adsorbents, bulk cuprous chemicals usually show a low efficiency. In order to create a great number of exposed active sites, a general approach is to load Cu­(I) on porous materials with a large surface area, for example, zeolites, − mesoporous silica materials, , and metal–organic frameworks (MOFs). − Notably, direct incorporation of Cu­(I) on porous materials needs an elaborative operation under an inert atmosphere, for the reason that the Cu­(I) sites can be easily oxidized, and then will lose its reactivity. Thus, a two-step process is preferable via (i) introduction of Cu­(II) onto the porous materials, such as active carbon, , zeolites, , and mesoporous silica materials, − and (ii) reduction of Cu­(II) to active Cu­(I) sites.…”
