The controlled synthesis of highly crystalline MoS 2 atomic layers remains a challenge for practical applications of this emerging material. We demonstrate a facile method to synthesize crystalline mono-layer / few-layered MoS 2 thin films at liquid-liquid interface which can be suitably transferred on substrates. The films are characterized for its crystal structure by XRD and for the morphology by SEM and TEM. MoS 2 nanosheet-graphene nanosheet (MoS 2 -GNS) hybrid films have been developed by the application of layer-by-layer (LbL) technique. Cyclic voltametry and other electrochemical characterization techniques reveal that the hybrid film electrode shows 10 specific capacitance of 282 Fg -1 at a scan rate of 20 mVs -1 . The as-obtained hybrid electrode is robust and exhibits much improved cycle life (> 1000), retaining over 93 % of its initial capacitance as revealed by galvanostatic charge/discharge studies. The confirmation of better performance as a supercapacitor of the composite was studied by Electrochemical Impedance Spectroscopy. These results indicate that MoS 2 -GNS hybrid is a promising candidate for the electrode material in supercapacitor applications. 15 Chemicals 110All of the reagents used herein were of analytical grade and used as received without any further purification.

Catalyst precursors, their reduction protocols and reaction conditions integrally influenced the activity and selectivity pattern in glycerol hydrogenolysis. Ru prepared from chloride precursor (Ru(Cl)/C−B) showed the maximum selectivity to C−C cleavage products EG (56 %) and methanol (17 %) with 23 % selectivity to 1,2‐PDO. While, that prepared from nitrosyl precursor (Ru(n)/C−B) showed higher selectivity to 1,2‐PDO (44 %) and lower to EG (42 %). The catalysts prepared either with chloride or nitrosyl precursors but reduced by H2 showed lower glycerol conversion (10‐11 %) than NaBH4 reduced catalysts. For these catalysts, 1,2‐PDO selectivity increased to 40–43 % along with the major formation of 2‐propanol (48‐49 %) and very less selectivities to C−C cleavage products. The lower activity of the H2 reduced catalysts can be related to their lower acidity and the bigger Ru metal particle size (3‐5 nm). For Ru(Cl)/C−B catalyst, glycerol conversion increased from 28–97 % with a rise in temperature from 180 to 250 oC also favoring 1,2‐PDO selectivity; indicating that C−O bond cleavage was favoured in comparison to C−C scission, at higher temperature.
