“…5,[13][14][15][16] Spinel Co 3 O 4 oxide nanoparticles are regarded as a crucial competitive ORR catalyst because of their superior stability and affordability than commercial Pt nanoparticles supported on carbon (Pt/C). [17][18][19][20][21][22][23][24][25] The spinel groups have a general formula, AB 2 O 4 , where A and B are divalent and trivalent metal ions, respectively. The structure is a cubic, closely packed array of oxygen atoms with A 2+ ions occupying eight tetrahedral sites and B 3+ ions occupying half of the octahedral sites.…”

“…Platinum (Pt) and its alloy nanoparticles are the most efficient catalyst; however, their high price, inferior durability, and severe surface poisoning are additional hurdles for commercialization 5,13–16 .
