Functionalization of metal–organic frameworks with cuprous sites using vapor-induced selective reduction: efficient adsorbents for deep desulfurization

Abstract

Efficient, controllable conversion of Cu(ii) to Cu(i) was realized on metal–organic frameworks by using a vapor-induced selective reduction strategy.

Boosting Oxidative Desulfurization of Model and Real Gasoline over Phosphotungstic Acid Encapsulated in Metal–Organic Frameworks: The Window Size Matters

“…The ODS started with the fast diffusion of DBT from the oil phase to the acetonitrile phase. At the same time, the highly porous MOF materials could enhance the adsorption capacity for organosulfur compounds and the cocatalyst, such as H 2 O 2 . Thus the PTA supported on the MOF can be oxidized to W VI ‐peroxo by the enriched H 2 O 2 , which can, consequently, oxidize the concentrated DBT to sulfide and sulfone .…”

Synthesis of bimetallic–organic framework Cu/Co-BTC and the improved performance of thiophene adsorption

“…So far, a bunch of adsorbents have been reported for desulfurization, such as metal oxides, 13 active carbon, 14 zeolites, [15][16][17] mesoporous materials 18,19 and metal-organic framework (MOF) materials. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Among them, MOFs are getting more and more interest in adsorption desulfurization in recent years because of the high specic surface areas, highly ordered threedimensional pore structures, and easy modication of pore size and shape. 20 Based on these advantages, some pristine MOFs have been investigated in adsorption desulfurization.…”

Adsorption desulfurization of model gasoline by metal–organic framework Ni3(BTC)2

“…MOFs, as a new type of porous inorganic-organic hybrid materials, are well known for the extra-high specific surface areas, highly ordered three-dimensional pore structures, and easy modification of pore size and shape [22,23] . Based on these advantages, some MOFs have been investigated in adsorption desulfurization [24][25][26][27][28][29][30][31][32] . Matzger et al .…”

“…This result was ascribed to the highest acidity of MIL-47(V), though the origin of acidity was not clear. Recently, some researchers made many effort s to improve the desulfurization performance by modifying the virgin MOFs material through introducing Cu + into pristine MOFs [26,27] , or supporting/encapsulating ionic liquid on MIL-101 (Cr) [28,29] , or introducing Br atoms into the organic ligands [30] . Compared with those effort s, the investigation on the effect of different metal ions of isostructural MOFs on adsorption desulfurization performance is relatively limited [25,31] , which is also very meaningful for the development of desulfurization adsorbents.…”
