Exploring Quality Criteria for the Computational Modeling of Heterogeneous Catalysts.

In this millennium computational modeling has become an essential tool to understand the performance of heterogeneous catalysts. In this concept paper, I focus on three different areas, namely theoretical methodology, model complexity, and comparison to experiment and highlight specific approaches and develop a hierarchy of simulation models. In general, higher quality approaches coincide with a significant increase in computational cost. Therefore, I focus on one specific example, namely the conversion of methane to methanol over Cu-exchanged zeolites and illustrate how a cost-benefit analysis can lead to a high-quality, cost-efficient model. I believe that this work can serve as a guideline for students starting to work in electronic structure calculations, will help researchers to more carefully choose their modeling methodology, and might help experimental researchers to better judge computational work presented to them.
