An SCM-10 molecular sieve, having an empirical chemical composition of “first oxide second oxide”, wherein a ratio by molar of the first oxide to the second oxide is less than 40, the first oxide is at least one compound selected from the group consisting of silica and germanium dioxide, the second oxide is at least one selected from the group consisting of alumina, boron oxide, iron oxide, gallium oxide, titanium oxide, rare earth oxides, indium oxide, and vanadium oxide, and the SCM-10 molecular sieve in a calcined form has an X ray diffraction pattern as substantially illustrated in the following table,
