Modeling and optimizing irradiance on planar, folded, and honeycomb shapes to maximize photocatalytic air purification

β-SiC alveolar foams as a structured photocatalytic support for the gas phase photocatalytic degradation of methylethylketone

“…Within the search for new photocatalytic media, porous or multichannel support materials such as honeycomb-shaped or square channel monoliths, have gained interest for combining the need for a good contact between the photocatalyst and the air, to the necessity to process high flow rates at a low pressure drop [5,6]. However, they suffer from poor irradiation distribution with a limited penetration depth within the monolith [7].…”

Two-Dimensional Modeling of an Externally Irradiated Slurry Photoreactor

“…[9] shows that there is an exponential relationship between the transmittance and the mass of catalyst per unit volume. The reaction considered in the present modeling work is the mineralization of a substrate, Sub, dissolved in water in the presence of oxygen, photocatalyst particles and irradiation.…”

“…Moreover, precise modeling often requires a complex analysis of the radiation field, along with modeling of the fluiddynamics and the reaction kinetics, thus producing integro-differential equations, which mostly involve demanding numerical solutions, so that extreme attention must be paid in order to avoid unreliable results. The development of simpler mathematical models is, however, possible by idealizing some factors but still getting reliable solutions, very close to the experimental recorded values [8,9].…”

Model‐Based Optimization of a Photocatalytic Reactor with Light‐Emitting Diodes

“…Moreover, many efforts have been made to improve the efficiency of photocatalytic processes by optimizing the operating conditions of photocatalytic reactors such as pH, catalyst loading, light intensity and wavelength, flow rates, and reactant concentrations [12][13][14][15]. In contrast, fewer reports exist on the optimization of the photocatalytic reactor equipment [16,17].…”
