Sustainable　synthesis　of　MWW　zeolites　have　been　the　focus　of　attention　but　still　a　significant　challenge.　In　this　study,　an　innovative　synthesis　strategy　of　the　EniRicerche-Boralite-1　(ERB-1)　precursor　is　reported　via　an　interesting　steam-environment　crystallization　method　(SEC).　Compared　with　the　conventional　hydrothermal　synthesis,　this　method　not　only　simplified　the　synthetic　process　but　also　reduced　85%　amount　of　boric　acid　and　solvent　and　half　amount　of　the　piperidine　(PI,　SDA,　structure-directing　agent).　Moreover,　the　crystallization　time　was　also　reduced　from　7　d　to　2　d.　The　Ti-MWW　prepared　with　this　ERB-1　precursor　showed　the　same　catalytic　performance　as　typical　post-synthesized　Ti-MWW　(Ti-MWW-PS)　in　the　liquid-phase　epoxidation　of　1-hexene　with　H2O2.　XRD　and　SEM　techniques　explained　the　effects　of　boron　content　and　crystallization　time　on　the　preparation　of　ERB-1.　The　physicochemical　properties　of　the　ERB-1　and　corresponding　Ti-MWW　in　different　preparation　conditions　were　investigated　systematically　by　the　FT-IR,　UV–vis,　ICP,　NH3-TPD　and　N2　absorption-desorption　techniques.　This　method　is　both　eco-friendly　for　the　synthesis　of　ERB-1　and　effective　for　the　preparation　of　MWW-type　zeolites　in　industrial　production　on　a　large　scale　in　the　future.　©　2018　Elsevier　B.V.
