An environmentally benign pathway for com. production of mol. hydrogen can be made by electrocatalytic water splitting, which requires highly active catalyst like Pt. Nowadays, 1T MoS2 is recognized as a good alternate to Pt in hydrogen evolution reaction (HER) by virtue of its dense active sites, hydrophilicity and enhanced electronic conductivity However the formation of such phase is still challenging as being 2H is the most stable phase of MoS2. Here, a simple hydrothermal approach is followed, wherein alkylated ammonium ion introduction between layers of MoS2, was employed for 1T phase enriched MoS2 formation, aiming to elucidate the influence of the intercalated ions on the interlayer expansion as well as the selective formation of the 1T phase. Me ammonium ion was found to be the most apt for 1T phase enrichment as over 70% was achieved and the resultant MoS2 exhibits magnificent HER activity with a low Tafel slope of 56 mV/dec and required just 270 mV overpotential to attain a c.d. of 10 mA cm-2 with robust durability. The optimum variations in interlayer, rich 1T phase formation are the key findings of this study. This investigation opens up new strategy i.e., interlayer expansion induced enrichment of 1T phase via alkylated ammonium ions will be highly useful for other 2D layered materials in near future for energy related HER applications. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0HPLC of Formula: 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.HPLC of Formula: 75-57-0
