Computational Investigation of Thermochemistry and Kinetics of Steam Methane Reforming on Ni(111) under Realistic Conditions

TL;DR: In this article, the reaction pathways and kinetics of steam methane reforming (SMR) over Ni(111) were investigated using plane wave density functional theory, and the thermochemical data were used to develop a microkinetic model of SMR that allows for the investigation of reforming pathways and the most abundant reaction intermediates on the catalyst surface at industrially relevant temperatures and pressures.
