Direct observation of dimethyl sulfide trapped by MOF proving efficient removal of sulfur impurities

Abstract

OMSs in HKUST-1 can strongly trap DMS even under humid conditions, which was directly proved by in situ single-crystal X-ray diffraction and Raman measurements.

A Cu(II)-BTC Metal-Organic Framework Modified Carbon Paste Electrode and Its Application as Electrochemical Sensor for Methanol Determination

“…56 In addition to the peaks mentioned before, it was observed the presence of diverse peaks at 35°−45°which indicated the existence of Cu and Cu x O in the Cu-BTC. 57 By comparing the XRD peak positions with the existing Cu-BTC MOFs previously reported in Cambridge Structure Database, [58][59][60][61][62][63][64] the Bragg reflection peaks of the solid obtained match with those presented for the structures of copper trimesate complexes of Cu-BTC MOF as show in Fig. 1S.…”

Direct Electrochemical Synthesis of Metal‐Organic Frameworks: Cu3(BTC)2 and Cu(TCPP) on Copper Thin films and Copper‐Based Microstructures

“…Additionally, all samples presented changes on their surface after the electrochemical MOF conversion into Cu 3 (BTC) 2 or Cu(TCPP), as shown in Figure 3 The calculated XRD pattern for Cu 3 (BTC) 2 is displayed in dark green near the x axis and the corresponding peaks were marked with an asterisk (*) on top of the green curve in a). This calculated XRD pattern was obtained from the Cambridge Crystallographic Data Centre [64] with the identifier FUNGAZ by Morita et al [65] The use of additives in the electrochemical synthesis of the Cu 2 O octahedra, and of the Cu 2 O and Cu dendrites, allows the growth of less favorable crystallographic planes, overcoming thermodynamic (octahedra) or kinetic (dendrites) barriers. [36,37,[41][42][43][44][45][46][47] These more unfavorable exposed planes dissolve faster by the applied bias, so more Cu 2 + ions are available for the MOF conversion, reacting more efficiently with the organic linker in the electrolyte during the partial MOF conversion though anodic oxidation.…”

Confining organic cations in metal organic framework allows molecular level regulation of CO2 capture

“…The refined structure of Cu-BTC is the same as that reported before. 49 In detail, the two Cu(II) ions are coordinated by four O atoms to form the CuII 2 (CRO 2 ) 2 paddle wheel unit, which connects with four phthalic acid molecules to generate three distinct cages (Figure S6), that is, the 26-hedron cage with an internal diameter of 1.86 nm (Cage I), the 14-hedron cage with an internal diameter of 1.494 nm (Cage II), and the inclined octahedron cage with an internal diameter of 1.127 nm (Cage III) (Figure S6b). Cage III is located at the top of the cell and connected to Cage I through a triangular window of length 0.801 nm.…”
