%X A new composite system is fabricated by depositing the TiO2 film on a silicon nanoporous pillar array (Si-NPA) and annealing at 500°C using the spin coating method. Such a composite system exhibits a uniform morphology with the micron-dimension pillar array. Photocatalytic properties are investigated based on the degradation of methyl orange dye solution, and the results show that the photocatalytic efficiency of such a nano-composite system is 1.7 times that of the TiO2/glass system. The enhancement of hotocatalytic efficiency is attributed to the large surface area of the TiO2/Si-NPA system.
