Claims
- 1. A multi-functional material with a photocatalytic function, comprising:a base; a photocatalytic layer having a photocatalytic function disposed on a surface of said base, photocatalytic layer including at least a surface layer exposed outwardly, said surface layer being composed of fine photocatalytic particles joined together with interstices defined therebetween at a predetermined porosity; and particles filled in said interstices which are smaller than the interstices, said particles having a diameter of less than 0.1 μm; said particles filled in the interstices defined between said photocatalytic particles having an average diameter which is ⅘ or less of the average diameter of said photocatalytic particles, and said particles filled in the interstices defined between said photocatalytic particles are made of a material having a vapor pressure higher than the vapor pressure of a material of said photocatalytic particles, and are condensed on necks between the photocatalytic particles.
- 2. A multi-functional material according to claim 1, wherein said particles filled in the interstices defined between said photocatalytic particles are made of tin oxide.
- 3. A multi-functional material with a photocatalytic function, comprising:a base; a photocatalytic layer having a photocatalytic function disposed on a surface of said base, said photocatalytic layer including at least a surface layer exposed outwardly, said surface layer being composed of fine photocatalytic particles joined together with interstices defined therebetween at a predetermined porosity; and particles filled in said interstices which are smaller than the interstices, said particles having a diameter of less than 0.1 μm; wherein said smaller particles comprise at least one of Cu in an amount of 0.7/g/cm2-10 g/cm2 and Ag in an amount of 0.05 g/cm2-1 g/cm2.
