Abstract:
1. A metal oxide nanoporous material which comprises two or more kinds of first metal oxides selected from the group consisting of alumina, zirconia, titania, iron oxide, rare-earth oxides, alkali metal oxides and alkaline-earth metal oxides, the metal oxide nanoporous material having nanopores, each with a diameter of 10 nm or smaller, and the metal oxides being dispersed homogeneously in a wall forming the nanopores, wherein, when a spectrum of a tested sample of the nanoporous material is measured at measurement points located in regions where the tested sample has an approximately equal thickness by energy dispersive X-ray spectroscopy using a transmission electron microscope with a 200 kV accelerating voltage and a 1.0 nm diameter of electron beam, and
