Diverse nitrogen-doped 2D layered mesoporous MoS2/reduced graphene oxide composites with superior structural features for enhancing the performance of lithium ion batteries

摘要: Abstract In this paper, we report the construction of nitrogen-doped 2D layered mesoporous molybdenum disulfide/reduced graphene oxide (meso-N-MoS2/rGO) hybrids via a nanocasting method using ammonium molybdate as source, thiourea sulfur and nitrogen modified KIT-6/rGO template. The as-prepared meso-N-MoS2/rGO is constituted homogeneously distributed ultrasmall few-layer MoS2 nanoparticles composited with N-modified nanosheets possesses large surface area high porosity. When being used anode materials for Li ion batteries (LIBs), obtained hybrid exhibits prominent electrochemical properties in terms specific capacity (1195.1 mA h g−1 at 100 mA g−1) superior rate performance (606.2 mA h g−1 1000 mA g−1). discharge still maintains 872.8 mA h g−1 even after 50 cycles. Such an intriguing mainly attributed to its porosity, area, strong coupling effect between uniform N-doped since N-doping small size can set up conductive bridges, abundant pyridine nitrogen, excellent conductivity. addition, provides networks, which ensure that lithium ions electrons have shorter transmission distance, thereby increasing their diffusion ease charge process volume effect. This work effective strategy synthesize meso-MoS2/rGO achieve significantly enhanced performance.
