Molybdenum sulfide (MoS2) has become a potential anode of lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to its high theoretical capacity and low cost. However, the volume expansion, poor electrical conductivity and dissolution of polysulfides in the electrolyte during the cycling process severely limited its applications. Herein, few-layered MoS2@N-doped carbon (F-MoS2@NC) was synthesized through a facile solvothermal and annealing process. It was found that the addition of N-doped carbon precursor could significantly promote the formation of few-layered MoS2 and improve the performances of lithium and sodium storage. A high reversible capacity of 482.6 mA h g−1 at a high current density of 2000 mA g−1 could be obtained for LIBs. When used as anode material for SIBs, F-MoS2@NC hybrids could maintain a reversible capacity of 171 mA h g−1 at a high current density of 1,000 mA g−1 after 600 cycles. This work should provide new insights into carbon hybrid anode materials for both LIBs and SIBs.

The quantitative production, of ethane, quinhydrone, and potassium cupric cyanide by a-c. electrolysis was studied in respect to conditions affecting yield. It was found that a good yield (about 90%) of quinhydrone was obtained by a-c. electrolysis, at low frequency and moderately high current density, of an aqueous solution of hydroquinone. This method of preparation has a distinct advantage in respect to space-time yield over the method of d-c. electrolysis. The current yield of potassium cupric cyanide at low current density (0.3 to 1.0 amp. per cm.2) using a.c. was in the neighbourhood of 88%. A-c. electrolysis was not found to indicate any particular advantage over d-c. electrolysis, as far as could be ascertained by comparing the ethane efficiency of the two processes.
