The present disclosure relates to a novel method of preparing a novel vanadosilicate molecular sieve, and a vanadosilicate molecular sieve and their derivatives prepared by the same method. The preparing method of a vanadosilicate molecular sieve includes forming a vanadosilicate molecular sieve by a hydrothermal reaction of a reaction mixture containing a silicon source, a base, a V 5+ -containing compound as a vanadium source, a reducing agent, a salt and water. |
