Abstract
Pencemaran air akibat limbah zat warna organik, seperti metilen biru (Methylene Blue, MB), memerlukan teknologi pengolahan yang efektif. Penelitian ini bertujuan menganalisis pengaruh delaminasi lanjutan dan variasi rasio komposit Ti3C2Tx MXene/Fe₃O₄ terhadap karakteristik, morfologi, dan aktivitas fotokatalitik dalam degradasi metilen biru. Ti3C2Tx yang selanjutnya disebut ”MXene” disintesis menggunakan metode Minimally Intensive Layer Delamination (MILD), kemudian sebagian sampel didelaminasi menggunakan dimetil sulfoksida (DMSO). Komposit MXene/Fe₃O₄ dan Del-MXene/Fe₃O₄ dibuat dengan rasio massa 1:2, 1:1, dan 2:1 melalui metode sonikasi. Karakterisasi dilakukan menggunakan XRD, SEM–EDX, Raman, BET, VSM, dan UV–Vis Spektrofotometer, sedangkan aktivitas fotokatalitik dievaluasi menggunakan spektrofotometer UV–Vis. Hasil karakterisasi menunjukkan bahwa delaminasi meningkatkan d-spacing dari 9,45 Å menjadi 15,95 Å serta luas permukaan dari 124,302 menjadi 174,659 m²/g, yang menunjukkan terbentuknya struktur lembaran yang lebih terbuka. Uji fotokatalitik menunjukkan bahwa Fe₃O₄ murni memiliki aktivitas terendah dengan degradasi sebesar 11,36%, sedangkan komposit Del-MXene/Fe₃O₄ rasio 1:2 memberikan performa terbaik dengan efisiensi degradasi sebesar 86,26% dan konstanta laju pseudo orde pertama sebesar 7,77 × 10⁻³ menit⁻¹. Hasil penelitian menunjukkan bahwa delaminasi lanjutan meningkatkan aksesibilitas situs aktif, sedangkan rasio Del-MXene/Fe₃O₄ 1:2 menghasilkan aktivitas fotokatalitik terbaik dalam degradasi metilen biru.

Water pollution caused by organic dye waste, such as methylene blue (MB), requires effective treatment technologies. This study aims to analyze the effect of further delamination and variations in the Ti₃C₂Tₓ MXene/Fe₃O₄ composite ratio on the characteristics, morphology, and photocatalytic activity for methylene blue degradation. Ti₃C₂Tₓ, hereinafter referred to as "MXene," was synthesized using the Minimally Intensive Layer Delamination (MILD) method, after which a portion of the samples was further delaminated using dimethyl sulfoxide (DMSO). MXene/Fe₃O₄ and Del-MXene/Fe₃O₄ composites were prepared with mass ratios of 1:2, 1:1, and 2:1 using the sonication method. Characterization was carried out using XRD, SEM–EDX, Raman, BET, VSM, and a UV–Vis spectrophotometer, while the photocatalytic activity was evaluated using a UV–Vis spectrophotometer. The characterization results showed that delamination increased the d-spacing from 9.45 Å to 15.95 Å and the surface area from 124.302 to 174.659 m²/g, indicating the formation of a more open layered structure. The photocatalytic test showed that pure Fe₃O₄ exhibited the lowest activity with a degradation efficiency of 11.36%, whereas the Del-MXene/Fe₃O₄ composite with a 1:2 ratio showed the best performance, achieving a degradation efficiency of 86.26% and a pseudo-first-order rate constant of 7.77 × 10⁻³ min⁻¹. The results indicate that further delamination increases the accessibility of active sites, while the Del-MXene/Fe₃O₄ composite with a 1:2 ratio exhibits the best photocatalytic activity for methylene blue degradation.
