Abstract

Gold nanoparticles are useful in many applications and therefore there is interest in having an accurate understanding and model of their growth process. In this work, we utilize the Finke-Watzky model of particle formation to develop a detailed population balance model. The model includes a novel approach to describe partial adsorption of stabilizers on the surface of growing nanoparticles by a modified Langmuir isotherm and takes particle interactions into account. Moreover, we derive a model reduction strategy to significantly decrease the simulation time required. We demonstrate the applicability of our model by estimating unknown model parameters and showing good alignment of the entire particle size distribution to measurement data of the synthesis as a function of time, including equilibrium constants of adsorption as well as growth mechanisms and growth rates.
