Disclosed is a method of preparing mesoporous silica nanoparticles using hydrothermal synthesis, including adding a transition metal when reacting a surfactant and a silica precursor. The mesoporous silica nanoparticles are high functional particles able to be used as an adsorbent, a sensor, a membrane, a catalyst and a catalyst support, thanks to their large surface area and nano-sized pores. The mesoporous silica nanoparticles are functionally advantageous in terms of increased material diffusion rate and reactivity, easy recycling after use as a catalyst and slow inactivation, compared to conventional mesoporous silica, and are prepared through a very simple process among methods of controlling the particle size of mesoporous silica to a nano size.
