《Plasma-etching enhanced titanium oxynitride active phase with high oxygen content for ambient electrosynthesis of ammonia》 was written by Kang, Shenghong; Wang, Jialu; Zhang, Shengbo; Zhao, Cuijiao; Wang, Guozhong; Cai, Weiping; Zhang, Haimin. COA of Formula: C4H12KNaO10This research focused ontitanium oxynitride phase plasma etching oxygen content ammonia electrosynthesis. The article conveys some information:
Here we report that the plasma-etching processed com. titanium nitride (TiN-PE, PE represents plasma-etching) that was first treated by ball-milling method (TiN-BM, BM represents ball-milling) is highly electrochem. active for the nitrogen (N2) reduction reaction (NRR) to NH3. The results demonstrate that the TiN-PE as NRR electrocatalyst can deliver a yield rate of NH3 of 3.32 × 10-10 mol s-1 cm-2 (4.1 mg h-1 g-1cat.) with a Faradaic efficiency of 9.1% at -0.6 V (vs. RHE) in 0.1 M Na2SO4 solution (pH = 3.2). The XPS anal. indicates that the titanium oxynitride (TiOxNy) with high oxygen content on TiN surface was significantly enhanced by this plasma-etching approach, which is electrocatalytically active species for NRR. The 15N isotopic labeling exptl. results using 15N2 as the feeding gas verify that the syntheized NH3 product during NRR is composed of 15N in 15NH+4 (the enrichement of 64%) and 14N in 14NH+4 (the enrichment of 36%), indicating that the NRR process follows the Mars-van Krevelen mechanism. In the experimental materials used by the author, we found Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5COA of Formula: C4H12KNaO10)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. COA of Formula: C4H12KNaO10 As a Biuret reagent, it is used to measure the protein concentration. Furthermore, it is used as laxative and is also used in food industry.
