ABSTRACTWe have performed first-principles density functional theory calculations to investigate how subsurface 3d transition metals M (M = Ni, Co, Fe, Ti, or V) affect the energetics and mechanisms of oxygen reduction reaction (ORR) on the outermost Pt mono-surface layer of Pt/M (111) surfaces. We found that the alteration of the ORR mechanism pathway can explain the activity enhancement for ORR on the Pt/M (111) surfaces.

In the present work, we have investigated the electrocatalytic activity of the oxygen reduction reaction (ORR), O2 + 4H+ + 4e− → 2H2O, for (Pt)n clusters (n = 1, 2, 3, 5, 7, 10 and 12) adsorbed on semiconducting (2H) and metallic (1T) MoS2 monolayers using first principles density functional theory.

Discovering active, stable and cost-effective catalysts for the oxygen reduction reaction (ORR) is of utmost interest for commercialization of fuel cells. Herein, we use density functional theory calculations to systematically study metal supported hexagonal boron nitride as ORR catalysts. Our results indicate that this strategy is a promising to increase the stability against CO poisoning as well as to activate inert h-BN toward the ORR.

Atomically dispersed Fe and Co on N-doped carbon were prepared as ORR and Zn–air battery catalysts, and the synergetic effect between Fe–N4 and Co–N4 was demonstrated by electrochemical results and density functional theory calculations.

Dispersive force corrected density functional theory is used to map the oxygen reduction reaction (ORR) kinetics of six kinds of graphyne (Gy) and graphdiyne (Gdy) systems (namely αGy, βGy, γGy, δGy, 6,6,12Gy, RGy and Gdy) with substitutional boron (B) atom doping.

Two dimensional (2D) conjugated metal organic frameworks (MOFs) which feature single atom catalysts are promising electrocatalysts to promote oxygen reduction reaction (ORR). Here, by means of density functional theory calculations...
