novel enzyme mimics. Compared to pure MoS2 nanosheets, the as‐prepared MoS2‐Pt3Au1 nanocomposites displayed enhanced peroxidase‐like activity. The nanocomposites also possessed well dispersibility and high stability in water. With these findings, a simple, fast and low‐cost colorimetric detection of phenol with high sensitivity and selectivity is developed, which is based on oxidative coupling reaction
基于MoS 2的纳米复合材料正在作为新型多功能材料出现。在这里,均匀的Pt 3 Au 1纳米颗粒(NPs)装饰的几层MoS 2纳米片被制造为新型酶模拟物。与纯MoS 2纳米片相比,制备的MoS 2 -Pt 3 Au 1纳米复合材料显示出增强的过氧化物酶样活性。纳米复合材料还具有良好的分散性和在水中的高稳定性。基于这些发现,开发了一种简单,快速,低成本的比色法检测苯酚,具有高灵敏度和选择性的方法,该方法基于苯酚和4-氨基安替比因在H 2存在下的氧化偶联反应O 2作为氧化剂形成粉红色产物。这项工作提供了一种MoS 2 -NP复合材料作为酶模拟物,可用于许多潜在的催化应用。
