MoS2 is a 2D semiconductor where exfoliation to single layer results in improved catalytic properties. However, its high surface energy can lead extensive aggregation, resulting degraded performance and stability. Combined with lack of dispersibility water, this represents pitfall for catalysis the aqueous phase. Herein, we present use nanoscopic layered silicates pillared cationic surfactant template growth interlayer space. This provides heterostructured nanoparticles ∼25 nm wide by 3–8 thick containing isolated layers. The nanohybrids retain disc-like morphology chemistry clays, providing good stability, while also access edge-sites layer. In addition significant enhancement dye degradation, molecular aggregation on highly charged clay interface comparable unmodified clays. These particles are ideal studies charge-transport properties confined layers, as well hierarchical self-assembly into functional materials. study paves way colloidal synthesis nanoparticulate heterostructures other materials, particularly particle exfoliation, covalent modification, stability concerns.
