Claim 0:
1. A catalyst structure comprising exsolved particles of Ni, Co and/or mixtures of Ni and Co in a perovskite metal oxide of formula (I):

(M1aM2b)(CoxNiyM3z)O3  (I)

wherein
M1 and M2 are each independently an alkali earth metal or a rare earth metal,
M3 is Ti or Cr,
0≤a≤1,
0≤b≤1,
0<a +b≤1,
0≤x<1,
0≤y<1,
0≤z<1,
x+y+z=1, and
at least one of x and y >0
wherein the exsolved Ni, Co or NiCo particles have an average particle diameter of from 2 to 50 nm; and
wherein the exsolved particles are supported on a residual perovskite metal oxide lattice of the perovskite metal oxide.
