Ti/BMMs　(Ti　supported　bimodal　mesoporous　silica)　catalysts　have　been　prepared　via　self-assembly　route　combined　with　ship-in-a-bottle　method.　The　recovery　and　recycling　performances　of　Ti/BMMs　were　investigated　in　the　epoxidation　of　cyclohexene.　In　order　to　the　evaluate　the　regeneration　methods　and　to　examine　the　deactivation　behaviors,　the　deactivated　Ti/BMMs　catalysts　were　washed　in　chloroform　or　calcinated　at　450　degrees　C　for　6　h　and　then　activity　of　the　recovery　catalysts　were　examined.　Meanwhile,　the　structure　features　and　surface　properties　of　the　regenerated　catalysts　were　characterized　by　X-ray　diffraction,　N-2-sorption　analysis,　scanning　electron　microscopy,　transmission　electron　microscopy,　Fourier　transform　infrared　spectroscopy,　thermogravimetric　analysis,　UV　visible　spectroscopy　and　X-ray　photoelectron　spectroscopy.　The　results　showed　that　the　typical　bimodal　mesoporous　structure　of　recycled　Ti/BMMs　catalysts　was　still　maintained,　and　the　phenomenon　of　Ti　leaching　during　the　catalytic　process　and　recovery　was　negligible.　In　particular,　spectroscopic　observations　indicated　that　the　effects　of　the　regeneration　methods　on　the　tetrahedrally-coordinated　Ti　species　and　catalytic　deactivation　were　remarkable.　The　main　reasons　were　related　to　the　polarities　of　used　solvents　during　recovery　tests,　the　environment　medium　of　adsorbed　water　inside　mesopore　channels　and　the　deposition　of　bulky　molecules　of　by-products　on　the　mesoporous　surface.　(C)　2014　The　Chemical　Industry　and　Engineering　Society　of　China,　and　Chemical　Industry　Press.　All　rights　reserved.
