get me specific individual crystal structure formulas (example: CuCo3) that may give good adsorption energy values for *OH adsorption for the oxygen reduction reaction(ORR). I am looking to find candidates that give an adsorption energy value of 0.9-1.1 eV relative to H2O and H2

do not retrieve fractional stoichiometries, do not mention vague families of materials. if you mention a family, give specific examples of materials in that family with full formulas. retrieve as many materials as you can in your research

you dont have to mention the exact atomic site. identify promising candidates. these may not include platinum based catalysts. they may include metal oxides, perovskites, double perovskites etc.

  1. no hard and fast conditions. just identify good possible ones
  2. bulk materials are preferable but again no limits
  3. search anywhere and everywhere

the materials dont have to be related to the ORR, nut you may guess that they are good for that

Based on my comprehensive research, I can now provide you with an extensive list of specific crystal structure formulas that may exhibit good OH adsorption energy values for oxygen reduction reaction (ORR) catalysis. Here are the promising candidates:
