In　this　report,　we　present　the　synthesis　of　yolk-shell　Co3O4@CuO　microspheres　followed　with　the　surface　modification　of　carboxyl-functionalized　graphene　quantum　dots　(donated　as　Co3O4@CuO@GQDs)　and　investigate　their　lithium　storage　properties.　Derived　from　metal-organic　frameworks　(MOFs),　the　obtained　yolk-shell　Co3O4@CuO　microspheres　exhibit　well-defined　microstructure　and　high　porosities.　The　yolk-shell　Co3O4@CuO　structure　is　designed　to　adapt　the　stepwise　lithium　insertion　mechanism　(first　in　CuO　shell　and　then　in　Co3O4　core).　In　addition,　the　GQDs　decorated　on　the　surface　of　Co3O4@CuO　microspheres　not　only　provides　larger　specific　surface　area,　more　active　sites　and　enhanced　electronic　conductivity,　but　also　works　as　a　buffer　to　alleviate　the　volume　expansion　and　a　reservoir　for　electrolyte　molecules　to　improve　the　ionic　conductivity.　Furthermore,　the　-COOH　groups　from　GQDs　exhibits　good　hydrophilicity　which　is　supposed　to　be　useful　for　the　combination　of　GQDs　with　Co3O4@CuO　and　also　shows　strong　affinity　to　Li+.　Based　on　the　above　merits　from　the　structural　and　compositional　design,　the　Co3O4@CuO@GQDs　anode　displays　enhanced　cyclability　and　superior　lithium　storage　performance.　Specifically,　compared　to　the　bald　Co3O4@CuO　microspheres　without　GQDs　which　suffer　from　a　severe　capacity　decline　with　an　inferior　capacity　of　414　mAh　g(-1)　after　200　cycles,　the　Co3O4@CuO@GQDs　anode　displays　an　initial　specific　capacity　of　816　mAh　g(-1)　and　a　high　reversible　charge　capacity　of　1054　mAh　g(-1)　after　200　cycles　at　0.1　A　g(-1).
