“…However, to our knowledge, the modeling study of catalytic cracking of hydrocarbons over Pt catalysts is still lacking. In order to understand the fundamental reaction mechanisms associated with hydrocarbon cracking reactions on Pt catalysts, first principle calculations are used widely, especially for low-molecular-weight hydrocarbons [24][25][26][27][28][29][30][31]. These research efforts provide insight at the molecular level for the chemistry involved in the catalytic cracking of linear hydrocarbons over Pt catalysts, which mainly focus on the elementary reaction dynamics over single-crystal metal surfaces.…”
