Adsorption of gas molecules on the surface of semiconductor nanoparticle
 pdf 

ABSTRACT

From the solution of diffusion equation, the concentration of the gas adsorbed on the semiconductor nanoparticle surface has been calculated. Dependences of the number of adsorbed gas molecules on sizes of the nanoparticle and gas molecule are given. The time dependence of the gas mass accumulated on the nanoparticle surface has been calculated. The thickness and the rate of formation of adsorption layer on the surface of ZnO and Co3O4 semiconductor nanoparticles are compared. Since the rate of accumulation of the gas mass on the ZnO nanoparticle surface is higher, it adsorbs ambient gases faster, and therefore is more promising as a gas-sensing material.

Keywords: semiconductor nanoparticles, gas adsorption, thickness of adsorption layer, accumulation of gas mass on the surface.
