This approach has been widely employed by Vlachos and coworkers to convert DFT energies to ∆ f H referenced to the global thermochemical network. Vorotnikov et al. used the method to construct a database of adsorbates for furan chemistry on Pd(111). Further, they used Eq. ( ) to determine the ∆ f H of all gas-phase species (that are not the references) with the G4 level of theory rather than using ATcT values. This application illustrates an alternative use of the approach where gas-phase species and adsorbates are computed with different levels of theory but can be combined in a single thermochemical network since both are referenced to the same network. Integrating the accurate ∆ f H of gas-phase species and the ∆ f H of adsorbates derived from DFT in a global thermochemical network is crucial when building coupled homogeneous/heterogeneous reaction mechanisms or for open-ended mechanism exploration with automated mechanism generation software . Some of the authors have used the method for the microkinetic modeling of the transient CO 2 methanation on Ni(111) or the temperatureprogrammed desorption of .
