Synthesis of Porous Catalyst Particles and Three-dimensional Reconstruction Analysis

Abstract

In this study, porous structured three-way catalyst particles were synthesized through a spray pyrolysis followed by heating processes using template particles. When nitrogen was used as the carrier gas, porous catalyst particles were synthesized while maintaining the pore structure of the particles. In addition, the internal structure of the synthesized porous catalyst particles was analyzed by using TEM Tomography, and the interconnected pore structures were confirmed inside the particles. Furthermore, the CO₂ adsorption rate results show that the introduction of porous structure contributes to the improvement of mass transfer coefficient.
