Introducing　advanced　conductive　nanoparticles　to　combine　with　metal-organic　frameworks　(MOFs)　as　electrode　is　emergingly　regarded　as　a　practical　and　efficient　approach　to　improve　the　capacitive　performance　of　supercapacitors.　Herein,　a　new　MOF　(ZrNi-UiO-66,　Nickel-zirconium　1,4-dicarboxybenzene)　is　designed　to　combine　with　carbon　quantum　dots　(CQDs)　to　form　a　composite　electrode　with　high　specific　capacitance,　in　which　the　charge　regulation　is　performed　to　facilitate　the　electronic　conduction　and　transfer.　Such　constructed　electrode　delivers　an　enhanced　electronic　conductivity　and　an　improved　specific　capacitance　of　2468.75　F　g−1@　1　A　g−1,　which　is　four　times　of　the　contrast　sample.　Meanwhile,　the　assembled　hybrid　supercapacitor　exhibits　an　increased　energy　density　and　power　density,　as　well　as　a　sustainable　stability　after　10,000　cycles　with　a　retention　rate　of　91.6　%.　Basing　on　the　study　of　advanced　characterizations　and　density　functional　theory　(DFT)　simulation,　the　mechanism　of　significantly　improved　specific　capacitance　can　be　elaborated　as　the　promote　electronic　conduction　caused　from　narrowed　band　gap　from　3.9　eV　or　0.41　eV–0.23　eV,　and　the　increased　charge　accumulation　at　the　Ni　sites　in　designed　MOFs.　This　work　provides　new　insights　for　the　design　and　construction　of　potential　energy　storage　materials　based　on　MOFs　and/or　advanced　carbon-based　materials.　©　2024　Elsevier　B.V.
