Based on a systematic first-principles analysis, we propose a modified parameterization of the UBI-QEP semi-empirical method able to reproduce DFT prediction within +-10% error. Such semi-empirical estimates for the barriers can provide most useful insight into complex reaction networks, where an exhaustive first-principles treatment is prohibitive.
