MoS2 nanoclusters/graphene composite (MoS2/GNs) was prepared by one-step hydrothermal strategy in which MoS2 nanoclusters were enwrapped by graphene nanosheets. MoS2/GNs electrode delivered discharge/charge capacities of 890 and 885 mA · h/g at 0.2 °C (200 mA g–1) after 300 cycles, as rechargeable Li ion batteries (LIBs) anode material, corresponding to a reversible charge capacity retention of up to 73.0%. When the current was adjusted to 5 C (5000 mA g–1), the material could still deliver discharge/charge capacities of 612 and 591 mA · h/g. The synergistic effects between MoS2 and graphene contributed to excellent electrochemical performance, which efficiently improved its electrical conductivity, and concurrently inhibited volume change of the MoS2 in the electrode.

Production Of Hydrogen

The energy crisis and environmental pollution have attracted much attention and have promoted researches on clean and sustainable hydrogen energy resources. With the help of highly active and stable transition metal nickel-based catalysts, the production of hydrogen from water electrolysis from electrolyzed water has become an inexpensive and efficient strategy for generating hydrogen energy. In recent years, heteroatom doping has been found to be an effective strategy to improve the electrocatalytic hydrogen evolution reaction (HER) performances of nickel-based catalysts in acidic, neutral, and alkaline media. This review will highlight many recent works of inexpensive and readily available heteroatom-doped nickel-based HER catalysts. The evaluation methods for the performances of HER catalyst will be briefly described, and the role of heteroatom doping and its application in nickel-based catalyst will be summarized. This article will also point out some heteroatom doping strategies, which may provide references and inspire the design of other catalysts with dopants.
