PROBLEM TO BE SOLVED: To provide a photocatalytic material having high catalytic effect and being easy to handle.SOLUTION: The photocatalytic material includes a porous material composed of a multiple oxide containing titanium and silicon. The porous material includes a base part and a protrusion structure part grown from the base part, and the atomic ratio of titanium to silicon, (Ti/Si) (Tiand Siare atomic percentages of titanium and silicon, respectively, in the protrusion structure part), is different from the atomic ratio of titanium to silicon, (Ti/Si) (Tiand Siare atomic percentages of titanium and silicon, respectively, in the base part). |
