In　this　work,　we　explore　the　suitability　of　several　density　functionals　with　the　generalized　gradient　approximation　(GGA)　and　beyond　for　describing　the　dissociative　chemisorption　of　methane　on　the　reconstructed　Pt(110)-(2×1)　surface.　The　bulk　and　surface　structures　of　the　metal,　methane　adsorption　energy,　and　dissociation　barrier　are　used　to　assess　the　functionals.　A　van　der　Waals　corrected　GGA　functional　(optPBE-vdW)　and　a　meta-GGA　functional　with　van　der　Waals　correction　(MS　PBEl-rVV10)　are　selected　for　ab　initio　molecular　dynamics　calculations　of　the　sticking　probability.　Our　results　suggest　that　the　use　of　these　two　functionals　may　lead　to　a　better　agreement　with　existing　experimental　results,　thus　serving　as　a　good　starting　point　for　future　development　of　reliable　machine-learned　potential　energy　surfaces　for　the　dissociation　of　methane　on　the　Pt(110)-(2×1)　surface.　©　2021　Chinese　Physical　Society.
