Abstract：

Pursuing　effective　and　generalized　strategies　for　modulating　the　electronic　structures　of　atomically　dispersed　nanozymes　with　remarkable　catalytic　performance　is　exceptionally　attractive　yet　challenging.　Herein,　we　developed　a　facile　“formamide　condensation　and　carbonization”　strategy　to　fabricate　a　library　of　single-atom　(M1-NC;　6　types)　and　dual-atom　(M1/M2-NC;　13　types)　metal-nitrogen-carbon　nanozymes　(M　=　Fe,　Co,　Ni,　Mn,　Ru,　Cu)　to　reveal　peroxidase-　(POD-)　like　activities.　The　Fe1Co1-NC　dual-atom　nanozyme　with　Fe1-N4/Co1-N4　coordination　displayed　the　highest　POD-like　activity.　Density　functional　theory　(DFT)　calculations　revealed　that　the　Co　atom　site　synergistically　affects　the　d-band　center　position　of　the　Fe　atom　site　and　served　as　the　second　reaction　center,　which　contributes　to　better　POD-like　activity.　Finally,　Fe1Co1　NC　was　shown　to　be　effective　in　inhibiting　tumor　growth　both　in　vitro　and　in　vivo,　suggesting　that　diatomic　synergy　is　an　effective　strategy　for　developing　artificial　nanozymes　as　novel　nanocatalytic　therapeutics.　©　2023　American　Chemical　Society.
