The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Silver(I) trifluoromethanesulfonate( cas:2923-28-6 ) is researched.HPLC of Formula: 2923-28-6.Sinha, Soumalya; Tran, Giang N.; Na, Hanah; Mirica, Liviu M. published the article 《Electrocatalytic H2 evolution promoted by a bioinspired (N2S2)Ni(II) complex at low acid concentration》 about this compound( cas:2923-28-6 ) in ChemRxiv. Keywords: nickel electrocatalyst hydrogen evolution reaction. Let’s learn more about this compound (cas:2923-28-6).
The electrochem. hydrogen evolution reaction (HER) is of great interest to advance fuel cell technologies. Although heterogeneous HER electrocatalysts are desired for practical energy devices, the development of mol. electrocatalysts is important to elucidate the mechanism and improve the activity of state-of-the-art HER catalysts. Inspired by the enzymic HER process promoted by [NiFe] hydrogenases, we synthesized a bioinspired NiII electrocatalyst that produces H2 from CF3CO2H at low acid concentrations (<0.043 M) in MeCN. Under these conditions, the turnover frequency for HER achieved herein is ~200,000 s-1. We propose that our NiII electrocatalyst follows a novel HER mechanism by undergoing a 2e- transfer process in a single step, followed by stepwise H+ transfer at low acid concentrations, and the increase in acid concentration changes the HER mechanism toward a concerted H+/e- transfer. Finally, we evaluated the HER activity of our catalyst by benchmarking its kinetic and thermodn. parameters vs. other reported HER electrocatalysts. Although many compounds look similar to this compound(2923-28-6)HPLC of Formula: 2923-28-6, numerous studies have shown that this compound(SMILES:O=S(C(F)(F)F)([O-])=O.[Ag+]), has unique advantages.
