Two
dimensional MoS2 nanosheets decorated with inorganic
nanoparticles (INPs) are emerging novel MoS2-based nanohybrids for tuning the intrinsic attributes of both components for fundamental
research and technological applications. However, the design and fabrication of
MoS2-INP nanohybrids
with tailor-made structure and functions remain a significant challenge. Herein
we report a general and controllable protocol to one-step synthesis of various MoS2-INP nanohybrids by
employing carboxylic MoS2 (MoS2-COOH)
nanosheets as a versatile support. The obtained MoS2-INP nanohybrids exhibit
good dispersibility, high reactivity and excellent processability. The size,
morphology and coverage density of INPs on the surface of MoS2-COOH can be readily controlled
by tuning the feed ratio. Control experiments reveal that the presence of carboxylic functional groups
plays a key role in controlling the structure
and properties of the resulted MoS2-INP nanohybrids.
In addition, ternary MoS2-based
nanohybrids can also be readily
prepared by this approach, as exemplified by the synthesis of MoS2-Fe3O4/Pt
nanohybrids, which simultaneously exhibit
excellent catalytic performance toward the reduction of 4-nitrophenol and favorable
magnetic separation capability. Considering the simple fabrication process, high
controllability of this protocol and excellent performance of the product, the
present work opens up enormous opportunities to large-scale production of
diverse MoS2-based nanohybrids for many technological applications.
