| 英文摘要 | MoS2-based hybrids have aroused great interest for their outstanding performance in the application fields of biochemical sensing, catalysis and energy storage. Herein, we present a facile strategy to fabricate hierarchical microtubes by cultivating a MoS(2)sheet-like nanostructure on polypyrrole microtubes (designated as PPy@MoS(2)microtubes) using MoO3@PPy micro-cables as self-sacrificial templates. Such a dissolution-regrowth mechanism is demonstrated for the formation of hierarchical PPy@MoS(2)microtubes by studying the morphology of the intermediate products in the process of the sulfidation reaction. The PPy microtubes are able to effectively improve the electrical conductivity of the hybrid architecture and greatly alleviate the agglomeration of the MoS(2)nanosheets. Notably, the sheet-like MoS(2)nanostructure can load more noble metal nanoparticles (NPs) owing to MoS(2)released photogenerated electrons irradiated by light. Then, metal (Ag, Au, and Pd) NPs are reduced andin situdecorated on PPy@MoS(2)microtubes, thus forming ternary PPy@MoS2@Ag, Au, and Pd nanohybrids, respectively. This decoration method also expands the wide range of application fields of PPy@MoS2. As a proof of application, the ternary PPy@MoS2@Au hybrids reveal excellent enzyme-like catalytic performance. Owing to the high coverage of Au NPs as well as one dimensional hierarchical MoS2-based ternary unique structures, the resultant PPy@MoS2@Au hybrid composites exhibited synergistically enhanced peroxidase-like catalytic activity relative to MoS2, MoS2@Au, and PPy@MoS(2)alone, demonstrating the remarkable prospects of MoS2-based hybrids in chemical/biological molecule sensing application. |
