Abstract：

Two-dimensional　(2D)　materials　with　intrinsic　pores　have　attracted　attention　for　catalytic　and　electronic　applications.　However,　a　significant　gap　exists　between　all-inorganic　2D　networks　with　inorganic　connectors　and　those　with　organic　connectors　due　to　the　greater　complexity　of　functionalizing　inorganic　molecules.　Addressing　this　gap,　we　present　a　new　class　of　2D　all-inorganic　porous　networks:　single-layer　cluster　ionic-chain　networks　(CINs),　constructed　by　using　PW10M2　(M　=　Mn,　Co)　polyoxometalate　(POM)　clusters　as　nodes　and　end-capping　agents　for　ionic　chains.　The　integration　of　POM　clusters　into　these　networks　significantly　alters　the　electronic　and　band　structures.　Notably,　the　Mn-based　CIN　exhibits　extremely　high　catalytic　activity,　achieving　a　toluene　oxidation　conversion　rate　of　over　1.45　mmol　g−1　h−1.　Calculations　suggest　that　POM　clusters　act　as　an　‘electron　buffer’,　stabilizing　electron　density　at　Mn　sites　and　lowering　the　activation　energy　for　toluene　oxidation.　This　development　showcases　POM　clusters　as　‘superatom’　capping　agents,　establishing　a　pathway　for　all-inorganic　2D　networks　that　could　advance　new　catalytic　materials　with　unique　electronic　properties.　©　The　Author(s)　2025.
