Organic cations, such as R4N+ (R = CH3-, C2H5-, and Pr-), are suggested as potential candidates to tune the activity and product selectivity of the CO2 reduction reaction (CO2RR). The stability of R4N+ species during the H evolution reaction (HER) is systematically examined by differential electrochem. mass spectrometry (DEMS), since the HER always occurs in parallel with the CO2RR in aqueous systems. Possible reaction mechanisms of R4N+ were studied systematically by changing the composition of electrodes materials (CuOx, glassy C, and polycrystalline Pt), size of cations, types of anions, and their concentration The authors’ DEMS results and combined ex situ H1 NMR anal. reveal that during the HER at all three electrodes the following occur: (i) R4NOH and R4NClO4 (R = CH3-, C2H5-, and Pr-), as well as Me4NCl, are stable, while Et4NCl and Pr4NCl are not. (ii) Widely distributed mass signals (from m/e = 2 to 150) are detected in solutions containing Et4NCl and Pr4NCl, which come probably from Et3N and Pr3N produced by the HER induced chem. reaction of R4N+. (iii) Small quantities of Et3NH+Cl– and Pr3NH+Cl– are produced in Et4NCl and Pr4NCl solution, resp., probably through Hoffman elimination. The Et3NH+Cl– and Pr3NH+Cl– will react with OH– produced from the HER and releases R3N, giving the false appearance that R4N+ is not stable under HER conditions. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Computed Properties of C4H12ClN).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Computed Properties of C4H12ClN
