Open-cell foams have been accepted as one of the most promising substrates in immobilized photoreactors due to high mass transfer efficiency and large specific area but did not show a significant advantage over other substrates. A real-geometry-based computational fluid dynamic model of the photoreactor packed with idealized restructured β-SiC foams for the gas-phase photodegradation of methylethylketone (MEK) using the rutile TiO₂ thick film is proposed to clarify the unanticipated inferior performance quantitatively. The difference in transparency of the substrate is demonstrated as the origin of inferior performance that the MEK conversion ratio with glass foams is 30.5% and 25.98% higher than those with opaque foams and with glass Raschig rings, respectively. Moreover, the semi-transparent substrate breaks through the limitation of the photoactivity with the foams of high cell density, that the MEK conversion could reach 11.1% when ρ_c = 45 ppi, improved by approximately 183% when compared to the opaque samples.

由于传质效率高和比表面积大，开孔泡沫已被认为是固定化光反应器中最有前途的基材之一，但与其他基材相比并没有显示出明显的优势。使用金红石 TiO ₂气相光降解甲乙酮 (MEK) 的理想化重构 β-SiC 泡沫填充光反应器的基于真实几何的计算流体动力学模型提出了厚膜以定量澄清意外的劣质性能。基板透明度的差异被证明是性能较差的根源，即使用玻璃泡沫的 MEK 转化率分别比使用不透明泡沫和玻璃拉西环的 MEK 转化率高 30.5% 和 25.98%。此外，半透明基材突破了高泡孔密度泡沫对光活性的限制，当ρ _c  = 45 ppi 时，MEK 转化率可达到 11.1% ，与不透明样品相比提高了约 183%。
