The invention provides a nanostructure material with metallic oxide including a product fabricated by the following steps: condensing silicon oxide or titanium oxide with a surfactant, obtaining a mesoporous silicon oxide or titanium oxide; mixing the mesoporous silicon oxide or titanium oxide with a metal or metallic compound and subjecting the mixture to a heterogeneous nucleation. According to another embodiment of the invention, the nanostructure material can also be fabricated by the following steps: subjecting silicon oxide or titanium oxide and a carbon black template to a calcination; mixing the results with a metal or metallic compound; and subjecting the mixture to a second calcinations. Further, in the invention, a method for detecting phosphorus-containing compounds employing the aforementioned nanostructure material is also provided.
