1. A monolith catalyst for reforming methane, the monolith catalyst comprising:
a monolith support;
a sintering inhibition layer formed by coating a surface of the monolith support with at least one element, wherein the at least one element is selected from elements belonging to Group 13, Group 15, or Group 16, and the at least one element belongs to Period 3 or higher; and
an active metal layer disposed on the sintering inhibition layer,
wherein,
the sintering inhibition layer is coated on the surface of the monolith support without using an alumina sol,
the active metal layer is sequentially present on the sintering inhibition layer,
content of the active metal layer has 0.5 to 2 parts by weight based on 100 parts by weight of the monolith support, and
a composition for the active metal layer is represented by Chemical Formula 1 below,
a(X)−b(Y)  [Chemical Formula 1]
wherein X is a catalytically active component comprising Co and any one or a mixture of two or more selected from the group consisting of Ni, Ru, and Rh, Y is a promoter Zr, and a and b are real numbers showing weight proportions of X and Y, respectively.
