PROBLEM TO BE SOLVED: To provide a silica-based material having high mechanical strength and a high specific surface area and excellent in resistance to acids and bases, a process for producing the same and a noble metal-supported material including the silica-based material.SOLUTION: A silica-based material comprises: silicon; aluminum; at least one fourth period element selected from the group consisting of iron, cobalt, nickel and zinc; and at least one basic element selected from the group consisting of alkali metal elements, alkali earth metal elements and rare earth elements, in which the silica-based material comprises 57.6 to 90 mol% of the silicon, 3.1 to 30 mol% of the aluminum, 0.75 to 15 mol% of the fourth period element and 2 to 36.6 mol% of the basic element, based on a total mole of the silicon, the aluminum, the fourth period element and the basic element. The silica-based material can be used as a catalyst support, and the noble metal-supported material can be used widely as a catalyst for chemical synthesis. |
