- W3045761452 abstract "The sluggish kinetics of oxygen reduction reaction (ORR), especially in acid media, seriously restrains the commercialization of direct methanol fuel cells. Herein, we synthesize a hierarchical Co3O4@N-doped partly-graphitized carbon wrapped by Ti3+-self-doped TiO2 nanoparticles with multiple crystal-phases (anatase and rutile TiO2) as catalysts (Co3O4@[email protected]2) for ORR in alkaline/acid media using ZIF-67 as a precursor. Co3O4@[email protected]2-0.3 (tetrabutyl titanate of 0.3 mL) exhibits the same peak potential (Epeak of 0.83 V, vs. RHE) as Pt/C in 0.1 M KOH and the comparable Epeak (0.69 V) to Pt/C (0.7 V) in 0.5 M H2SO4. Synergistic effects between tetrahedral Co2+ (Co3O4) and Ti3+ (MP-TiO2) chiefly contribute to the high ORR activity. ORR stabilities of Co3O4@[email protected]2-0.3 are higher than those of Pt/C in alkaline/acid media, attributing to that [email protected]2 shell can protect active sites (tetrahedral Co2+ and N species) from corrosion and deactivation. Moreover, the dissociated adsorption of O2 on Ti3+ may facilitate the O2 protonation (Ti4+–OOHads−) to accelerate electron-transfer process and ORR kinetics in acid electrolyte, while acid-pickling of CoOx@NGC improves the stability of Co3O4@NGC to further smooth ORR process. This study provides a promising strategy for the design of highly-active and stable ORR catalysts in both alkaline and acid electrolytes." @default.
