Three-dimensional (3D) aerogels based on growth of tetragonal molybdenum disulfide (1T-MoS) on hydrothermally acid-treated porous carbon (HAPC) derived from sugarcane bagasse and reduced graphene oxide (rGO) composites were hydrothermally synthesized. The resultant composites, HAPC/MoS/rGO (1:2:0.5) and HAPC/MoS/rGO (1:1:0.5) were evaluated as an anode for lithium-ion batteries (LIBs) and as a supercapacitor, respectively. This HAPC/MoS/rGO (1:2:0.5) composite delivers a high reversible discharge capacity of 952 mAh g after 200 cycles at a current density of 0.2 A g and outstanding high-rate capability as an anode for LIBs. While another composite HAPC/MoS/rGO (1:1:0.5) reveals the best performance as a supercapacitor by delivering a specific capacitance of 385 F g at 1 A g. Such an excellent and stable performance of the composites in energy storage can be ascribed as the synergistic effect of three-dimensional aerogel consisting of 1T-MoS nanosheets, graphene sheets, and porous carbon. The 1T-MoS layered structured nanosheets are tightly lying on the surface of HAPC, making their strong contact with each other and therefore reducing the diffusion path for both electrons and lithium ions. While the electrical conductivity of the composite system is enhanced by the graphene sheets.

基于1T-MoS2在功能化分级多孔碳/还原氧化石墨烯上原位生长的三维气凝胶用于储能


水热合成了基于四方二硫化钼（1T-MoS）在源自甘蔗渣和还原氧化石墨烯（rGO）复合材料的水热酸处理多孔碳（HAPC）上生长的三维（3D）气凝胶。所得复合材料 HAPC/MoS2/rGO (1:2:0.5) 和 HAPC/MoS2/rGO (1:1:0.5) 分别作为锂离子电池 (LIB) 阳极和超级电容器进行评估。这种 HAPC/MoS/rGO (1:2:0.5) 复合材料在 0.2 A g-1 的电流密度下循环 200 次后可提供 952 mAh g-1 的高可逆放电容量，并且作为锂离子电池阳极具有出色的高倍率性能。而另一种复合材料 HAPC/MoS/rGO (1:1:0.5) 则展现了超级电容器的最佳性能，在 1 A g 电流下的比电容为 385 F g。该复合材料在储能方面如此优异和稳定的性能可以归因于由1T-MoS纳米片、石墨烯片和多孔碳组成的三维气凝胶的协同效应。 1T-MoS层状结构纳米片紧密地位于HAPC的表面，使它们彼此紧密接触，从而减少了电子和锂离子的扩散路径。而石墨烯片增强了复合系统的导电性。
