The Stability

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.

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.

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.

Insulating Properties

Using density functional theory calculations with van der Waals corrections, we have investigated the stability and electronic properties of monolayer hexagonal boron nitride (hBN) on the Ni (111) surface. We have found that hBN can bind either strongly (chemisorption) or weakly to the substrate with metallic or insulating properties, respectively. While the more stable configuration is the chemisorbed structure, many weakly bound (physisorbed) states can be realized via growth around an hBN nucleus trapped in an off-registry position. This finding provides an explanation for seemingly contradictory sets of reports on the configuration of hBN on Ni (111).
