The invention relates to the material filed, especially a ferromagnetic TiO2 semiconductor material which comprises a substrate, and a TiO2 layer arranged on the substrate. The TiO2 layer is a cellular nanostructured array stacked in a hexagon and having a uniform profile. The nanoparticle of the TiO2 layer is 3-5 nm. The material preparation method comprises: cleaning a substrate; forming a single layer colloid crystal template on a silicon substrate; immersing the single layer colloid crystal template in a precursory sol; taking the single layer colloid crystal template out and immersing the single layer colloid crystal template in dichloromethane, dissolving away a polystyrene template, and forming a cellular TiO2 nano array material. The method employs a single layer colloid crystal as a template, and successfully prepares a cellular TiO2 nanostructured array periodically arranged and having a uniform profile through a solution maceration method, wherein the material possesses greater ferromagnetic proper
