Abstract
Ushbu ishda Nano-SiO₂@[DPSSP][Cl]₂ deb belgilangan yangi sulfon kislotasi-funksionalizatsiyalangan kremniy asosidagi gibrid nanokatalizator mezoporoz kremniy ramkasiga organik ion funksionalligini kovalent immobilizatsiya qilish orqali muvaffaqiyatli sintez qilindi. Tayyorlangan katalizatorning strukturaviy, morfologik, termal va sirt xususiyatlari FT-IR, FE-SEM, XRD, azot adsorbsiyasi-desorbsiyasi (BET/BJH) va termogravimetrik tahlil (TGA) yordamida har tomonlama o‘rganildi. FT-IR spektrlari kremniy yuzasiga sulfon kislotasi va organik funktsional guruhlarning muvaffaqiyatli qo‘shilishini tasdiqladi, EDX tahlili esa Si, O, C, N, S va Cl elementlarining mavjudligini tasdiqladi. Elektron mikroskopiyasi taxminan 9 dan 31 nm gacha bo‘lgan o‘lchamlarga ega bir tekis taqsimlangan nanopartikullarni aniqladi. XRD tahlili kristallit o‘lchamlari 20 dan 37 nm gacha bo‘lgan gibrid katalizatorning asosan amorf tabiatini ko‘rsatdi.References
