This　study　developed　a　facile　approach　for　the　fabrication　of　dual　MgO-loaded　carbon　foam　(DMCF)　via　carbonization　of　a　cured　MgO/cyanate　ester　resin　mixture,　which　underwent　self-foaming　of　the　resin　followed　by　the　carbothermal　reduction　of　MgO.　The　features　of　the　prepared　DMCF　prepared　were　characterized　by　FESEM,　TEM,　XRD,　FTIR,　XPS　and　so　on,　and　the　effects　of　adsorption　conditions,　adsorption　isotherms,　kinetics,　and　thermodynamics　on　malachite　green　(MG)　removal　using　the　DMCF　as　adsorbents　were　investigated　through　batch　adsorption　experiments.　Results　demonstrate　that　the　DMCF　possesses　a　unique　dual　loading　of　MgO　particles　which　are　not　only　loaded　onto　its　foam　walls　but　also　filled　within　the　walls　with　a　graphene-wrapped　core-shell　structure.　The　experimental　maximum　adsorption　capacity　of　MG　reaches　up　to　1874.18　mg/g　with　a　partition　coefficient　of　10.87　mg/g/mu　M.　The　adsorption　process　can　be　better　described　with　Langmuir,　pseudo-second-order,　and　intraparticle　diffusion　models.　Moreover,　the　DMCF　exhibits　a　removal　percentage　of　84.85%　after　five　reuses,　indicating　that　it　is　an　efficient　and　promising　adsorbent　for　MG　adsorption.
