The following are all paragraphs of the method：The model of the Pd-Pt catalyst is constructed from the Crystallography Open Database, and the calculated lattice constant is 3.905 Å,39 which agrees well with the experimental values of 3.903 Å.40 The Pd-Pt (111) crystal plane was selected as the surface model for investigation. A p(2 × 2) expansion with four layers was constructed, and a 15 Å vacuum gap between slabs was added. The bottom two layers were fixed, and the top two were allowed to relax.
All theoretical calculations were performed using a plane wave-based DFT method implemented in Vienna Ab-initio Simulation Package (VASP),41,42 using the projected augmented wave (PAW) method.42,43 The exchange-correlation energy was treated within the generalized gradient approximation and Perdew-Burke-Ernzerhof functional (GGA-PBE). The DFT-D3 methodology raised by Grimme was used to describe the van der Waals correction.44 All-electron plane-wave basis sets with an energy cutoff of 450 eV. The Brillouin zone of the k-point grid was sampled with a 3 × 3 × 1 Monkhorst-Pack for the geometry optimization of the surface. Energy tolerances were 10-5 eV and 10-7 eV for geometry optimization and the transition state calculation. The force on each atom is less than 0.02 eV/Å. The transition state (TS) analyses were applied to find an approximate TS through the climbing image nudged elastic band (CI-NEB) method45 and optimized until the force was less than 0.05 eV/Å via the Dimer method.46 All steady states and transition states were further verified by vibrational frequency analysis.
To understand the strength of the adsorption between the gas molecules and the catalyst surface, the adsorption energy (Eads) was calculated according to the following formula:
\mathrm{E}_{\mathrm{(ads)}}\mathrm{=\ }Eadsorbate/surface-Eadsorbate-Esurface (1)
\mathrm{G(gas)\ =\ E(ele)\ +\ ZPE+RT-TS} (2)
\mathrm{G(solid)\ =\ E(ele)\ +\ ZPE+RT-TS} (3)
Where, Eele is the system’s electron energy in the ground state. ZPE is the zero-point energy. T is the temperature. S is the system’s entropy, and R is the molar gas constant.
The energy barrier (Ea) and reaction energy (∆G) is calculated as follows:
\mathrm{Ea\ \ =\ ETS\ -\ EFS} (4)
\mathrm{∆G = ETS - EFS (5)
Where, GIS, GTS, and GFS represent the Gibbs free energies of the initial, transition, and final states.

The following are all paragraphs of the method, with suggested modifications to enhance the language's precision, conciseness, and coherence, while adhering to the ACS Catalysis journal's standards for academic language:

The model of the Pd-Pt catalyst was constructed from the Crystallography Open Database, yielding a calculated lattice constant of 3.905 Å, which agrees well with the experimental values of 3.903 Å (I-II). The Pd-Pt (111) crystal plane was selected as the surface model for investigation. A p(2 × 2) expansion with four layers was constructed, and a 15 Å vacuum gap between slabs was added. The bottom two layers were fixed, and the top two were allowed to relax (III).

All theoretical calculations were performed using a plane wave-based density functional theory (DFT) method implemented in the Vienna Ab-initio Simulation Package (VASP), using the projected augmented wave (PAW) method (IV-VI). The exchange-correlation energy was treated within the generalized gradient approximation and Perdew-Burke-Ernzerhof functional (GGA-PBE), with the DFT-D3 methodology raised by Grimme used to describe van der Waals correction (VII-IX). All-electron plane-wave basis sets with an energy cutoff of 450 eV were used, with the Brillouin zone of the k-point grid sampled with a 3 × 3 × 1 Monkhorst-Pack for the geometry optimization of the surface. Energy tolerances were set to 10-5 eV and 10-7 eV for geometry optimization and the transition state calculation, with the force on each atom required to be less than 0.02 eV/Å. The transition state (TS) analyses were applied to find an approximate TS through the climbing image nudged elastic band (CI-NEB) method, and optimized until the force was less than 0.05 eV/Å via the Dimer method. All steady states and transition states were further verified by vibrational frequency analysis (X-XI).

To assess the strength of adsorption between gas molecules and the catalyst surface, the adsorption energy (Eads) was calculated using the following formula (XII):

E_(ads) = E_(adsorbate/surface) - E_(adsorbate) - E_(surface) (1)

The energy barrier (Ea) and reaction energy (∆G) were calculated using the following formulas (XIII-XIV):

Ea = E_(TS) - E_(FS) (4)
∆G = E_(TS) - E_(FS) (5)

Where, E_(ele) is the system’s electron energy in the ground state, ZPE is the zero-point energy, T is the temperature, S is the system’s entropy, and R is the molar gas constant. G_(IS), G_(TS), and G_(FS) represent the Gibbs free energies of the initial, transition, and final states, respectively (XV).

Overall, the modified text now reads more precisely, concisely, and coherently while adhering to the ACS Catalysis journal's standards for academic language. Let me know if you have any further questions or concerns.

The following is the conclusion: In summary, we proposed a reaction pathway for condensing toluene and butadiene over a Pt-Pd (111) catalyst to reveal the most promising path of origin coking formation during dehydrogenation at the atom scale. The result demonstrated two optimal routes, and the rate-limiting elementary reactions are phenyl hydrogen dissociation (S20→S21). Further studies verified on the surface of six precious metals found that the elementary reaction energy barrier of phenyl hydrogen dissociation (S20→S21) can be used as a descriptor of coke formation, which is in good agreement with the experimentally measured TG of coke formation. Guided by the key rate-limiting elementary reactions, we further find the intrinsic properties of the catalyst (d-band center energy, atomic spacing of surface) as descriptors.
Subsequently, the effect of free radicals on the coke formation process was studied using the descriptor. It was found that the hydroxyl radical significantly reduced the rate-limiting energy barrier by 0.47 eV, and the hydrogen radical significantly increased the rate-limiting energy barrier by 0.60 eV, which was in good agreement with the experimental conclusion, which further proved the reliability of the descriptor. Our results are helpful for the directional design and screening of anti-coking catalysts during bio-oil HDO.

In summary, we proposed a reaction pathway for condensing toluene and butadiene over a Pt-Pd (111) catalyst, revealing the most promising path of origin coking formation during dehydrogenation at the atom scale (I). Our results demonstrate two optimal routes, with the rate-limiting elementary reaction being phenyl hydrogen dissociation (S20→S21) (II). Further studies on the six precious metals' surfaces found that the energy barrier of phenyl hydrogen dissociation (S20→S21) can be used as a descriptor of coke formation, which is in good agreement with the experimentally measured thermogravimetry (TG) of coke formation (III). Guided by the key rate-limiting elementary reactions, we identified the intrinsic properties of the catalyst, such as the d-band center energy and atomic spacing of the surface, as descriptors (IV).

Subsequently, we studied the effect of free radicals on the coke formation process using the descriptor. Our results showed that the hydroxyl radical significantly reduced the rate-limiting energy barrier by 0.47 eV, while the hydrogen radical significantly increased the rate-limiting energy barrier by 0.60 eV, which is in good agreement with the experimental conclusion, further validating the reliability of the descriptor (V-VI).

Our findings provide valuable insights into the directionally designing and screening of anti-coking catalysts for bio-oil HDO (VII).
