1. A catalyst for preparing a light olefin, the catalyst comprising:
a porous zeolite;
clay;
an inorganic oxide binder; and
Ag2O and P2O5 which are supported in internal micropores and/or on a surface of the porous zeolite,
wherein 15 wt % or more and 40 wt % or less of the clay; and 5 wt % or more and 20 wt % or less of P2O5 supported in the internal micropores and on the surface of the porous zeolite are included, with respect to 100 wt % of the catalyst, and
wherein the catalyst is configured to prepare a light olefin by catalytic cracking of a mixed raw material including naphtha and methanol.
