1. A catalyst comprising a metal oxide and a molecular sieve having a topological pore structure in a crystal form, the metal oxide being concentrated on the surface of the molecular sieve , wherein the crystal grains of the molecular sieve expose at least three families of crystal planes, and no more than 30% of the meta oxide is distributed on the family of crystal plane having relatively the largest channel size in topology among the three families of crystal planes.
