On-line mass spectrometry investigation of the reduction of carbon dioxide in acidic media on polycrystalline Pt

Influence of adsorption processes on the CO2 electroreduction: An electrochemical mass spectrometry study

“…We have previously reported on the formation of methane, formaldehyde, formic acid and methanol, for the reduction of CO 2 and CO on polycrystalline platinum in HClO 4 , using in situ electrochemical mass spectrometry (EC/MS or DEMS) [26]. The previously proposed mechanism is similar to the one reported by Hori and coworkers on copper in neutral media [15].…”

“…Our preliminary work [26] conducted on the CO and CO 2 reduction on a polycrystalline Pt electrode in acidic media, has shown some interesting results, such as the presence of methane and methanol. In this work, we have investigated the behavior of CO and CO 2 on Cu polycrystalline surfaces using EC/MS, as well as the products of their electroreduction, from the region of hydrogen evolution to a more negative potential region.…”

Fixation of CO2 by Electrocatalytic Reduction and Electropolymerization in Ionic Liquid–H2O Solution

“…[8][9][10][11] This reaction has been studied on different electrodes, inlcuding metallic cathodes and semiconductors, and carbon electrodes modified with porphyrins or phthalocyanines containing different transition metals. [12][13][14][15][16][17][18] Titanium dioxide (TiO 2 ), in particular, is one of the most widely used and promising materials in electrocatalytic applications as a result of the strong reducing power of its redox couple as well as its high electrostability and easy preparation. [19][20][21] Revealing the surface structures that activate the reduction of CO 2 will provide fundamental knowledge for the design of electrocatalysts which reduce CO 2 efficiently.…”

“…The direct electrochemical reduction products of CO 2 reported to date include methane, methanol, ethanol, formaldehyde, formic, oxalic and lactic acid, and malate. [11][12][13][14][15][16][17][18][29][30][31][32][33][34][35] However, we are not aware of any other reports on the direct electrochemical synthesis of complex organic compounds from CO 2 . We report here for the first time the electrocatalytic synthesis of low-density polyethylene from CO 2 on a nanostructured (ns)TiO 2 film electrode by controlled potential electrolysis in [EMI]BF 4 -H 2 O at ambient temperature and pressure.…”

Electrochemical quartz crystal microbalance study on carbon oxides adsorption in the presence of electrosorbed hydrogen on Pd alloys with Pt and Rh

“…In general the product of CO 2 or CO adsorption can be a mixture of various compounds, including linearly and bridge bonded CO molecules [3,6,7,14,15,19,20,[24][25][26][27]29,30,[34][35][36][37][38][39]46,47,50,51,53], COOH [2,[5][6][7][8][9]16,17,25,37,50] and CHO [22,42] radicals and other species (CH 2 [18], CH [42], COH [6,20,21,23,42], or even C radicals [4,42,52]). Some authors support the opinion stated by Breiter [14] that the products of CO 2 and CO adsorption are the same.…”
