Organic　and　inorganic　entities　have　been　hybridized　using　3-aminopropyltriethoxysilane　(APTES)　linker　for　the　synthesis　of　three　novel　organic-inorganic　hybrid　catalysts　[Cu(ii),　Co(ii)　and　Ni(ii)].　During　the　course　of　the　synthesis,　the　static　inorganic　moiety　was　functionalized　with　versatile　imine　(CN)　groups.　The　prepared　catalysts　were　characterized　by　spectral　techniques　(EDS,　FT-IR,　DR　UV-Vis.,　29Si　CP/MAS　NMR,　powder-XRD　and　ESR),　thermal　study　(TG-DTG)　and　surface　studies　(SEM　and　AFM).　The　reported　catalysts　are　significant　because　of　their　geometrical　and　dispersive　surface　properties.　The　synthesised　catalysts　were　tested　with　cyclohexane　oxidation　reactions　using　H2O2,　to　make　the　catalytic　system　eco-friendly.　Compared　to　the　previously　reported　catalysts,　the　present　catalysts　have　shown　better　cyclohexane　conversion　and　selectivity,　and　are　also　cost　effective.　Among　the　three　catalysts　studied,　Cu(ii)　catalyst　showed　the　maximum　conversion　efficiency　(44%)　with　product　selectivity　of　29%　cyclohexanol　and　71%　cyclohexanone.　Because　of　the　combination　of　interesting　structural　properties　and　acceptable　catalytic　property　with　better　selectivity　and　environment　benign　character　along　with　a　low　cost,　these　hybrid　catalysts　could　be　the　best　future　catalysts　for　cyclohexane　oxidation.　©　2014　the　Partner　Organisations.
