Formation of an Ag/MoS2 composite structure through photothermal conversion

Precious metal nanoparticle composite two-dimensional materials have attracted widespread attention due to their excellent photothermal properties. A new method for selective modification of silver nanoparticles on atomic layered molybdenum disulfide (MoS 2 ) is presented. An Ag/MoS 2 composite structure is formed under the continuous irradiation of an 808 nm laser. The heat generated by the photothermal conversion of the MoS 2 nanosheets plays a major role in the growth of silver nanoparticles. The Ag/MoS 2 composite structure is analyzed via the combination of the absorption spectrum, scanning electron microscopy, particle size distribution, and Raman spectroscopy. The photothermal conversion can drive nanometer composite heterogeneous material growth.
