シリカ系材料及びその製造方法、並びに貴金属担持物及びそれを触媒として用いるカルボン酸類の製造方法

摘要

A silica-based material comprising:
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,
wherein the silica-based material comprises 42 to 90 mol% of the silicon, 3 to 38 mol% of the aluminum, 0.5 to 20 mol% of the fourth period element and 2 to 38 mol% of the basic element, based on a total mole of the silicon, the aluminum, the fourth period element and the basic element.
