Synthesis of monodisperse MoS$_{2}$ nanoparticles by the template method

Monodisperse molybdenum disulfide nanoparticles were synthesized in mesopores of spherical silica particles ($m$SiO$_2$) ) served as a template. First, the pores of $m$SiO$_2$ particles were impregnated with the precursor (ammonium tetrathiomolybdate solution). Then, the reduction of the filler in thermodynamically equilibrium conditions in H$_2$S/H$_2$ atmosphere was carried out. The template material ($\alpha$-SiO$_2$) was selectively etched from the composite $m$SiO$_2$/MoS$_{2}$ particles with HF to obtain individual MoS$_{2}$ nanoparticles. The mean size of MoS$_{2}$ nanoparticles determined by microscopic methods was found to be 3.5 nm. According to dynamic light scattering data, the nanoparticles had low size scatter (18%).
