Abstract

Pada penelitian ini telah berhasil disintesis material komposit GO@CuO/HKUST-1 dengan metode solvotermal dalam pelarut DMF:etanol:air pada suhu 100 ℃ selama 10 jam. CuO disintesis dengan kalsinasi HKUST-1 pada suhu 550 ℃ selama 4 jam. Penambahan CuO divariasikan dengan massa 10 dan 20% dari massa HKUST-1 hasil sintesis. Adanya penambahan komposit GO dilakukan secara in situ dengan massa 10% dari massa hasil sintesis CuO/HKUST-1. Seluruh material kemudian dikarakterisasi dengan XRD dan FTIR, sedangkan karakterisasi SEM-EDX hanya dilakukan pada material HKUST-1, CuO(10)/HKUST-1, dan GO@CuO(10)/HKUST-1. Material hasil sintesis diuji kinerja adsorpsi pada suhu ruang, pH netral, dan konsentrasi adsorbat 50 mg/L dengan variasi waktu kontak 10, 20, 30, 40, 50, dan 60 menit. Kinerja adsorpsi material dalam penghilangan CR menunjukkan bahwa penambahan komposit GO dapat meningkatkan kapasitas adsorpsi dengan nilai sebesar 25,911 mg/L. Semua material hasil sintesis mengikuti kinetika orde dua semu. Uji fotokatalitik menunjukkan bahwa penambahan GO pada material mampu menghasilkan pengurangan kadar CR lebih tinggi dibandingkan dengan HKUST-1 murni. Persentase pengurangan tertinggi adalah GO@CuO(10)/HKUST-1. Hal ini menandakan komposit GO@CuO/HKUST-1 dapat diaplikasikan pada adsorpsi dan fotokatalitik pewarna congo red.

In this research, the composite material GO@CuO/HKUST-1 has been successfully synthesized using the solvothermal method in the solvent DMF:ethanol:water at a temperature of 100 ℃ for 10 hours. CuO was synthesized by calcining HKUST-1 at 550 ℃ for 4 hours. The addition of CuO was varied with a mass of 10 and 20% of the mass of synthesized HKUST-1. The addition of GO composite was carried out in situ with a mass of 10% of the mass resulting from the CuO/HKUST-1 synthesis. All materials were then characterized with XRD and FTIR, while SEM-EDX characterization was only carried out on HKUST-1, CuO(10)/HKUST-1, and GO@CuO(10)/HKUST-1 materials. The synthesized material was tested for adsorption performance at room temperature, neutral pH, and an adsorbate concentration of 50 mg/L with varying contact times of 10, 20, 30, 40, 50, and 60 minutes. The adsorption performance of the material in CR removal shows that the addition of GO composite can increase the adsorption capacity by a value of 25,911 mg/L. All synthesized materials follow pseudo second order kinetics. Photocatalytic tests showed that the addition of GO to the material was able to produce a higher reduction in CR levels compared to pure HKUST-1. The highest removal percentages respectively were GO@CuO(10)/HKUST-1. This indicates that the GO@CuO/HKUST-1 composite can be applied for adsorption and photocatalytic use of congo red dye.
