| مستخلص: | Heteroatom doping is considered an effective way to enhance the catalytic activity of MoS2nanosheets (NSs). In the paper, dual-metal doping was proposed to incorporate Fe and Co into hierarchical MoS2ultrathin NSs, which grew directly on polypyrrole microtubes (Fe, Co–MoS2@PPy), for the enhanced enzyme-like catalytic reaction. The particular hollow tubular structure realized effective electron transfer. The doped Fe and Co tuned the electronic architecture of the MoS2NSs to enhance the enzyme-like catalytic activity. The abundant exposed void spaces facilitated ion diffusion/penetration between the PPy interlayer and Fe–Co doped MoS2shell, leading to heterostructured synergistic effects. Therefore, the synthesized Fe and Co–MoS2@PPy composites showed remarkable catalytic activity. The high catalytic efficiency of Fe and Co–MoS2@PPy was confirmed with the reaction of tetramethylbenzidine (TMB) and H2O2for visible detection. The blue color disappeared after adding glutathione (GSH). Thus, this procedure was used as a convenient way to detect GSH with a detection limit of 0.76 μM. The dual-metal-doped strategy was confirmed to improve the performance of MoS2nanocomposites and could be used as a promising matrix for other applications, such as electrochemical energy conversion, medical diagnosis, and others. |
