The　development　of　metal　organic　frameworks　(MOFs)-based　composites　is　a　research　topic　of　high　importance　because　these　composites　have　great　potential　for　wide　utilization　in　energy　transfer　and　environment　protection.　Herein,　a　series　of　CuS@NOTT-101　composites　have　been　successfully　fabricated　through　a　convenient　MOFs-templated　in　situ　vulcanization　strategy.　Highly　dispersed　ultrafine　CuS　particles　evenly　embedded　on　the　surface　or　within　the　pore　structure　of　the　resulting　composite　frameworks,　which　is　beneficial　for　introducing　hierarchical　architecture　and　exclusive　active　sites.　Remarkably,　the　optimal　composite　possesses　the　highest　adsorption　capacity　of　500　mg　g(-1)　for　RhB　6G　at　a　low　concentration　(30　mg/L)　among　the　previously　reported　MOFs/MOF-based　composites　and　reveals　an　outstanding　performance　toward　the　hydrogen　evolution　reaction　(HER)　with　a　small　Tafel　slope　of　78　mV　dec(-1)　as　well　as　good　cycling　stability　over　100　h.　Given　the　established　structural　and　compositional　designability　of　MOFs,　these　results　herald　the　appearance　of　multifunctional　composites　whose　location　of　active　sites　and　hierarchical　structure　are　precisely　controlled,　at　the　microscale　level.
