Claim 0:
1. A multicomponent metal oxide catalyst,
wherein,
the multicomponent metal oxide catalyst has a perovskite structure,
the multicomponent metal oxide catalyst is MgTiO3, CaTiO3, BaTiO3, or SrTiO3, wherein the Ti site of the MgTiO3, CaTiO3, BaTiO3, or SrTiO3 is partially substituted with an ionic form of Ni,
the multicomponent metal oxide catalyst has no nickel oxide (NiO), and
the multicomponent metal oxide catalyst is represented by the following Formula (1):

MTi1-xNixO3-δ  Formula (1)

wherein x is 0<x<0.03, δ is 0<δ<0.10, and M is Sr, Mg, Ca, or Ba,
wherein the ionic form of Ni has a coordination number lower than six and an oxidation number of +2, and δ is determined to maintain neutrality of the multicomponent metal oxide catalyst.
