Abstract

Pemakaian bahan bakar fosil dapat meningkatkan kadar CO2 di atmosfer. Gas CO2 dapat direduksi menggunakan material fotokatalis komposit CuO/AC. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan AC terhadap morfologi dan sifat fotokatalis untuk mendegradasi CO2 menjadi metanol. Sintesis CuO dilakukan menggunakan metode sol gel. Sementara itu, sintesis nanokomposit CuO/AC dilakukan menggunakan metode hidrotermal, lalu dilakukan uji fotokatalis reduksi CO2 menjadi metanol. Pengujian yang dilakukan adalah BET, XRD, FTIR, SEM, UV-Vis, GCMS dengan durasi penelitian adalah 5 bulan. Komposit CuO/AC berhasil disintesis, terbukti dari pengujian XRD yang terdeteksi adanya fasa CuO dan karbon. Ikatan karbon dan CuO terdeteksi pada pengujian FTIR. Pada pengujian SEM, CuO berbentuk nanorods dan AC berbentuk serpihan. Hasil EDS menujukkan bahwa terdapat unsur tembaga, oksigen, karbon dan nitrogen. Penambahan AC dapat meningkatkan energy band gap dari CuO hingga 1.780 eV. Penambahan AC dapat meningkatkan yield metanol komposit CuO/AC hingga 473.05 μmol/g katalis. Kata Kunci: CO2, Fotokatalis, Metanol, Komposit CuO/AC. =================================================================================================== The use of fossil fuels can increase CO2 levels in the atmosphere. CO2 gas can be reduced using CuO/AC composite photocatalyst material. This study aims to determine the effect of adding AC on the morphology and properties of the photocatalyst to degrade CO2 into methanol. CuO synthesis was carried out using the sol gel method. Meanwhile, the synthesis of CuO/AC nanocomposite was carried out using the hydrothermal method, then a photocatalyst test was carried out to reduce CO2 to methanol. The tests carried out were BET, XRD, FTIR, SEM, UV-Vis, GCMS with a study duration of 5 months. The CuO/AC composite was successfully synthesized, as evidenced by the XRD test which detected the presence of CuO and carbon phases. Carbon and CuO bonds were detected in the FTIR test. In the SEM test, CuO is in the form of nanorods and AC is in the form of flakes. The EDS results show that there are elements of copper, oxygen, carbon and nitrogen. The addition of AC can increase the energy band gap of CuO up to 1,780 eV. The addition of AC can increase the yield of CuO/AC composite methanol up to 473.05 mol/g catalyst.
