Abstract
The increasing emission of carbon dioxide (CO₂) has become one of the primary contributors to global warming, creating a growing need for effective and economical adsorbent materials. This study aimed to synthesize Zeolite-Y from Kasongan clay, Yogyakarta, using the Microwave-Assisted Hydrothermal (MAH) method and to evaluate its characteristics and effectiveness as a CO₂ adsorbent. The synthesis process involved clay preparation, NaOH activation, microwave heating, hydrothermal crystallization, washing, and drying. The synthesized material was characterized using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). CO₂ adsorption tests were conducted using adsorbent masses of 2, 3, and 4 g, flow rates of 5, 10, and 15 L/min, and contact times of 2, 3, and 4 min. The characterization results showed that the MAH synthesis altered the XRD diffraction pattern, as indicated by the appearance of a new diffraction peak at 2θ = 24.35° and the formation of a sodium aluminosilicate phase as an intermediate toward Zeolite-Y formation. The FTIR spectra confirmed the presence of characteristic aluminosilicate bonds, including Si–O–Si, Si–O–Al, and the Double Six Ring (D6R), which is a characteristic feature of the Faujasite (FAU) framework. SEM-EDS analysis revealed the predominance of Na, Si, Al, and O as the principal framework elements of the synthesized zeolite. The highest CO₂ adsorption efficiency reached 60.23% using 4 g of adsorbent, a 15 L/min flow rate, and a 4 min contact time. These findings demonstrate that the Microwave-Assisted Hydrothermal (MAH) method successfully produced Kasongan clay-based Zeolite-Y with promising potential as a CO₂ adsorbent. Keywords: Zeolite-Y, Microwave-Assisted Hydrothermal (MAH), Kasongan clay, CO₂ adsorption, XRD, FTIR, SEM-EDS. Peningkatan emisi karbon dioksida (CO₂) menjadi salah satu penyebab utama pemanasan global sehingga diperlukan material adsorben yang efektif dan ekonomis. Penelitian ini bertujuan untuk mensintesis Zeolite-Y berbasis tanah liat Kasongan, Yogyakarta menggunakan metode Microwave-Assisted Hydrothermal (MAH) serta menganalisis karakteristik dan efektivitasnya sebagai adsorben CO₂. Proses sintesis meliputi preparasi tanah liat, aktivasi menggunakan larutan NaOH, pemanasan microwave, kristalisasi hidrotermal, pencucian, dan pengeringan. Material hasil sintesis dikarakterisasi menggunakan X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), dan Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). Pengujian adsorpsi CO₂ dilakukan dengan variasi massa adsorben 2, 3, dan 4 gram, laju alir 5, 10, dan 15 L/menit, serta waktu kontak 2, 3, dan 4 menit. Hasil karakterisasi menunjukkan bahwa sintesis MAH menghasilkan perubahan pola difraksi XRD yang ditandai dengan munculnya puncak baru pada 2θ = 24,35° serta pembentukan fase natrium aluminosilikat sebagai fase antara menuju Zeolite-Y. Spektrum FTIR mengonfirmasi terbentuknya ikatan Si-O-Si, Si-O-Al, dan Double Six Ring (D6R) sebagai ciri struktur Faujasite (FAU), sedangkan hasil SEMEDS menunjukkan dominasi unsur Na, Si, Al, dan O sebagai penyusun utama kerangka zeolit. Pengujian adsorpsi menunjukkan efektivitas penyerapan CO₂ tertinggi sebesar 60,23% pada massa adsorben 4 gram, laju alir 15 L/menit, dan waktu kontak 4 menit. Hasil penelitian menunjukkan bahwa metode Microwave-Assisted Hydrothermal (MAH) berhasil menghasilkan Zeolite-Y berbasis tanah liat Kasongan yang berpotensi sebagai adsorben CO₂. Kata kunci: Zeolite-Y, Microwave-Assisted Hydrothermal (MAH), tanah liat Kasongan, adsorpsi CO₂, XRD, FTIR, SEM-EDS.
