Direct hydrogenation of CO₂ to ethanol at ambient conditions using Cu(i)-MOF in a dielectric barrier discharge plasma reactor

Abstract

The Cu(I)-MOF catalyst was applied to the selective hydrogenation of CO2 to ethanol in a continuous-flow DBD plasma reactor. At an ambient condition, as high as 41.2% CO2 was converted to ethanol (selectivity up to 62.9%).

Fabrication of a Cu(i)-carboxylate metal–organic framework by reduction of metal nodes for an azide–alkyne “click” reaction

“…In CuH 2 DOBDC, the asymmetric stretch of the carboxylic vibration peak appeared at 1595 cm −1 , while the symmetric stretch peak presented two distinct bands at 1425 and 1376 cm −1 . 25 Consequently, the observed splitting values of 170 cm −1 and 219 cm −1 in CuH 2 DOBDC correspond to bridging and monodentate characteristics, respectively. In addition, the spectra of CuH 2 DOBDC exhibited a peak at 1670 cm −1 attributed to the carbonyl stretching vibration of DMF.…”

Reinforced Volumetric Discharge by Tuning Permittivity and Spatial Scale Intensified Pulse Current for Efficient CO2 Reduction

“…The waveform distributions in applied voltage and current reflect, to some extent, the CO 2 reduction capabilities of the different packing systems. ,, As shown in Figure a, in the empty reactor, the peak current in the sinusoidal superposition was 21.1 mA. After the introduction of Al 2 O 3 particles, the pulsed current almost disappears while the sinusoidal current is enhanced.…”

Atomic/molecular layer deposition strategies for enhanced CO2 capture, utilisation and storage materials

“…Its moderate CO binding energy facilitates the formation of a crucial intermediate, CH 2 O* for C 2+ products from the electroreduction of CO 2 . 312,325–328 Various modification strategies, such as catalyst design/composition and cell design, have been utilized to enhance the active site, surface binding energy, and surface defects, thereby altering the product distribution. To achieve enhanced product selectivity, Suominen and colleagues, for the first time, showed the electrocatalytic reduction of CO 2 on ALD Cu-based catalysts, specifically CuS x thin films grown by ALD directly on gas diffusion electrodes (GDE).…”
