Aerogel nanoparticles which originated from organic silica in bagasse ash are unique because the silanol groups present on the silica surface can be replaced with other functional groups according to the application. Another uniqueness of the aerogel nanoparticles is the large surface area and pore structure, thus making the aerogel suitable as a sensory material. The combination of the ability to adsorb and the addition of electromagnetic properties can make this material useful as a sensor. In this research, we focused on the optimization of the synthesis of aerogel-based sensors by doping nickel (Ni) nanoparticles to create a highly sensitive and selective sensor material. The synthesis of aerogel nanoparticles was carried out using ambient pressure and alkaline extraction under atmospheric conditions. The aerogel was doped by replacing the silanol group (Si-OH) with Ni. The synthesized Ni-doped aerogel possesses a combination of microporous, mesoporous, and macroporous structures which contributed to its high pore density, pore volume, and surface area. The Ni-doping provides an electromagnetic effect that enhanced the sensory properties on the surface of the aerogel. The findings suggest that the Ni-doped aerogel is a promising material for a sensor application. [ABSTRACT FROM AUTHOR] |
