In　this　study,　the　hydrothermal　method　was　used　to　synthesize　MIL-101(Cr),　and　activated　carbon　(AC)　with　different　content　was　incorporated　in　to　MIL-101(Cr),　thereby　obtaining　AC-MIL-101(Cr)　composite　material　with　a　huge　specific　surface　area.　The　physical　properties　of　MIL-101(Cr)　and　AC-MIL-101(Cr)　were　characterized　by　powder　X-ray　diffraction　(PXRD),　scanning　electron　microscopy　(SEM),　thermogravimetric　analysis　(TGA),　nitrogen　adsorption　and　desorption　and　specific　surface　area　testing,　and　ethanol　vapor　adsorption　performance　testing.　The　results　show　that　with　the　increase　of　activated　carbon　content,　the　thermal　stability　of　AC-MIL-101(Cr)　is　improved.　Compared　with　the　pure　sample,　the　BET　specific　surface　area　and　pore　volume　of　AC-MIL-101(Cr)　have　increased.　In　the　relative　pressure　range　of　0-0.4,　the　saturated　adsorption　capacity　of　AC-MIL-101(Cr)　to　ethanol　vapor　decreases　slightly.　It　is　lower　than　MIL-101(Cr),　but　its　adsorption　rate　is　improved.　Therefore,　AC-MIL-101(Cr)/ethanol　vapor　has　a　good　application　prospect　in　adsorption　refrigeration　systems.　The　exploration　of　AC-MIL-101(Cr)　composite　materials　in　this　paper　provides　a　reference　for　the　future　application　of　carbon-based/MOFS　composite　adsorbent/ethanol　vapor　working　fluid　in　adsorption　refrigeration.
