Abstract：

Creating　useful　chemicals　or　fuels　from　CO2　is　one　of　the　most　promising　ways　to　reach　carbon　neutral.　In　this　work,　through　the　formation　of　Lewis　acid　sites,　a　string　of　boron-atom-coordinated　Ru　single-atom　catalysts　(SACs),　namely　RuBxN4-x@TiN　(x=0–4),　were　constructed,　and　their　CO2　reduction　reaction　(CO2RR)　was　systematically　studied.　The　results　show　that　o-RuB2N2@TiN,　p-RuB2N2@TiN,　and　RuB3N1@TiN　are　able　to　efficiently　inhibit　the　competitive　hydrogen　evolution　reaction　(HER)　and　activate　CO2,　with　a　potential-determining　step　lower　than　0.7　eV　and　high　selectivity　for　CH4　generation.　This　work　shows　that　the　synergistic　effect　of　B　and　Ru　atoms　are　able　to　effectively　improve　the　catalytic　activity,　which　is　expected　to　offer　a　possible　tactic　for　the　sensible　creation　of　effective　CO2RR　catalysts.　©　2024
