High-throughput screening of promising bifunctional catalysts for OER/ORR in disulfides
Designing efficient OER/ORR electrocatalysts is important for energy storage and conversion. In this paper, based on density functional theory (DFT), the TM@MS2 doping system consisting of 184 transition metal (TM) atoms was studied and screened on the basis of 8 TMDs structures, in order to find the ideal OER/ORR catalyst. Stability analyses showed that some of the catalysts were thermodynamically and electrochemically stable. By using ΔGO* values to screen catalysts, a new screening method, 11 ideal bifunctional catalysts, 8 ideal OER catalysts, and 7 ideal ORR catalysts were finally screened, with a high screening rate of 73.6 %. Among them, Rh@NbS2 has the lowest overpotential of 0.27 V in OER reaction and Rh@ZrS2 has the lowest overpotential of 0.21 V in ORR reaction. More importantly, it was found that Fe@NbS2 can be used as a good bifunctional catalyst at a much lower cost than precious metal catalysts. The high cORRelation between the coordination descriptor φ and the ΔGO* value of the catalysts also further confirms the accuracy of our use of the ΔGO* value as a screening criterion. This screening strategy is not only efficient, but also greatly reduces the cost and provides some theoretical support for subsequent experiments.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
