[QE-users] Guidance Required for modelling CO2 adsorption on CaO

2023-11-27 Thread Saiyed Tasnim Md Fahim
Hello Team, I need some guidance for modelling CO2 adsorption on CaO surface. My sample is Ni/CaTiO3/CaO and CO2 is captured in the CaO. Bulk phase is calcite (CaCO3) and the surface is monodentate carbonate. I want to build this model using DFT, but don't know where to start. Could you please t
