摘要
In this work,we set out to elucidate the light-harvesting properties of various random and ordered photocatalyst supports(PSs)with different macropore sizes.To accomplish this,we propose two studies of increasing relevance,enabled by computed tomography(CT)reconstructions and raytracing COMSOL Multiphysics simulations:(a)a 360-degree light release study approximating a PS situated within a compound parabolic concentrator(CPC)or cylindrical LED reactor with open ends;and(b)the same systemas before but with closed ends.The ordered geometry is of interest,as it can be 3D printed at scale with a tailored morphology and porosity,and it can potentially be refined using machine learning models to optimize its light-harvesting properties.As will be shown,the local volumetric light absorption(LVLA)data suggests that an ordered PSwith amore open pore interior and a smaller pore exterior would begin to approach the more isophotonic light-harvesting properties of random PSs.
