Abstract

Indonesia menghasilkan 619,28 juta ton emisi karbon yang berasal dari sektor industri dan penggunaan bahan bakar fosil, belum termasuk land use change pada tahun 2021. Salah satu solusi yang dinilai cukup efektif adalah proses adsorpsi dan reduksi CO2 dengan penggunaan semikonduktor perovskite. Untuk mengatasi kekurangan perovskite CsPbBr3, hadirlah Polyacrylonitrile (PAN) sebagai solusi yang menjanjikan karena eksistensinya dalam aplikasi adsorpsi CO2. Berdasarkan hal tersebut, penelitian ini bertujuan untuk mengetahui rasio komposisi terbaik antara PAN dan CsPbBr3 sehingga bisa menciptakan nanofiber PAN/CsPbBr3 yang optimal dalam mengadsorpsi CO2 dan menjadi properti elektrokimia. Digunakan empat variasi rasio komposisi massa antara PAN dan CsPbBr3, yaitu 0,5:1; 1:1; 2:1; 3:1. Berdasarkan pengujian XRD, FTIR, dan EDX, didapatkan nanofiber PAN/CsPbBr3 murni tanpa adanya impurities. Pengujian XRD juga menunjukkan semua variasi komposisi memiliki ukuran kristal yang bagus dengan ukuran kristal paling optimal milik variasi 2:1 sebesar 13,1144 nm. Morfologi pada hasil SEM menunjukkan, semakin tinggi komposisi PAN pada nanofiber PAN/CsPbBr3, maka diameter fiber akan semakin besar dan begitu juga beadsnya. Berdasarkan uji BET, komposisi PAN dan CsPbBr3 berpengaruh signifikan terhadap luas permukaan adsorpsinya dengan 2:1 menjadi rasio paling optimal dengan luas permukaan 16,724 m2/g dan ukuran pori 2,066 nm. Hal itu juga sejalan dengan hasil uji adsorpsi CO2, dimana variasi komposisi 2:1 memiliki kemampuan adsorpsi CO2 tertinggi, mencapai 8,92 mmol/g. Berdasarkan pengujian CV, semua variasi komposisi dari nanofiber PAN/CsPbBr3 dapat menjadi properti elektrokimia dan berpotensi menghasilkan produk kimia tertentu ketika digunakan untuk reduksi CO2 dengan proses fotokatalisis. Dari puncak-puncak yang terlihat pada setiap variasi komposisi juga menunjukkan tidak adanya pengaruh negatif penambahan PAN terhadap CsPbBr3. Dengan demikian, penelitian ini berhasil membuktikan nanofiber PAN/CsPbBr3 kemampuan adsorpsi CO2 yang baik dan memiliki band gap optimal untuk properti elektrokimia dengan variasi komposisi 2:1 menjadi variasi paling optimal dari segi karakterisasi, kemampuan adsorpsi, dan properti elektrokimia

Indonesia produces 619.28 million tons of carbon emissions originating from the industrial sector and the use of fossil fuels, not including land use changes in 2021. One solution that is considered quite effective is the CO2 adsorption and reduction process using perovskite semiconductors. To overcome the shortcomings of CsPbBr3 perovskite, Polyacrylonitrile (PAN) is present as a promising solution because of its existence in CO2 adsorption applications. Based on this, this research aims to determine the best composition ratio between PAN and CsPbBr3 so that it can create PAN/CsPbBr3 nanofibers that are optimal in adsorbing CO2 and have electrochemical properties. Four variations of the mass composition ratio between PAN and CsPbBr3 were used, namely 0.5:1; 1:1; 2:1; 3:1. Based on XRD, FTIR and EDX testing, pure PAN/CsPbBr3 nanofibers were obtained without any impurities. XRD testing also showed that all composition variations had good crystal sizes with the most optimal crystal size belonging to the 2:1 variation of 13.1144 nm. The morphology in the SEM results shows that the higher the PAN composition in the PAN/CsPbBr3 nanofiber, the larger the fiber diameter and so are the beads. Based on the BET test, the composition of PAN and CsPbBr3 has a significant effect on the adsorption surface area with 2:1 being the most optimal ratio with a surface area of 16,724 m2/g and a pore size of 2,066 nm. This is also in line with the results of the CO2 adsorption test, where the 2:1 composition variation had the highest CO2 adsorption capacity, reaching 8.92 mmol/g. Based on CV testing, all variations in the composition of PAN/CsPbBr3 nanofibers can have electrochemical properties and have the potential to produce certain chemical products when used for CO2 reduction using the photocatalysis process. The peaks seen in each composition variation also show that there is no negative effect of PAN addition on CsPbBr3. Thus, this research succeeded in proving that PAN/CsPbBr3 nanofiber has good CO2 adsorption capabilities and has an optimal band gap for electrochemical properties with a composition variation of 2:1 being the most optimal variation in terms of characterization, adsorption ability and electrochemical properties.
