Development　of　the　high　activity,　promoter-free　catalysts　for　carbonyl　sulfide　(COS)　hydrolysis　is　important　for　the　efficient　utilization　of　various　feedstocks.　In　this　study,　the　Cu-based　metal-organic　framework　HKUST-1　is　synthesized　by　a　simple　and　mild　anodic-dissolution　electro-chemical　method.　The　physical　and　chemical　properties　of　the　samples　are　characterized　by　several　techniques,　including　scanning　electron　microscopy,　X-ray　diffraction,　Brunauer-Emmett-Teller　analysis　and　X-ray　photoelectron　spectroscopy.　The　results　reveal　that　the　synthesis　voltage　plays　a　crucial　role　in　controlling　the　morphology　of　the　resulting　HKUST-1.　The　obtained　samples　function　as　novel　catalysts　for　the　hydrolysis　of　COS.　A　high　efficiency,　approaching　100%,　can　be　achieved　for　the　conversion　of　COS　at　150　degrees　C　over　the　optimal　HKUST-1　synthesized　at　25　V.　This　is　significantly　higher　than　that　of　the　sample　prepared　by　the　traditional　hydrothermal　method.　Additionally,　the　effects　of　the　water　temperature　and　the　flow　velocity　on　the　hydrolysis　of　COS　are　also　investigated　in　detail.　Finally,　a　possible　reaction　pathway　of　COS　hydrolysis　over　HKUST-1　is　also　proposed.　This　work　represents　the　first　example　of　MOFs　applied　to　the　catalytic　hydrolysis　of　COS.　The　results　presented　in　this　study　can　be　anticipated　to　give　a　feasible　impetus　to　design　novel　catalysts　for　removing　the　sulfur-containing　compounds.　(C)　2017,　Dalian　Institute　of　Chemical　Physics,　Chinese　Academy　of　Sciences.　Published　by　Elsevier　B.V.　All　rights　reserved.
