Judul: Sintesis Nanokomposit ZnO/Carbon Dots dari Bubuk Kopi sebagai Fotokatalis untuk Mendegradasi Pewarna Methylene Blue
Abstrak: Carbon Dots (CDs) disintesis dari bubuk kopi dengan menggunakan metode hidrotermal. Nanokomposit Zinc Oxide (ZnO)/Carbon Dots (CDs) disintesis dengan menggunakan metode ultrasonikasi. Morfologi permukaan, komposisi kimia dan struktur kristal dari nanokomposit ZnO/CDs secara berturut-turut dikarakterisasi menggunakan scanning electron microscopy (SEM), spektroskopi Fourier transform infrared (FTIR) dan X-ray diffraction (XRD). Sifat optik Carbon Dots dilihat menggunakan spektroskopi UV-Vis. Aktivitas fotokatalis dari nanokomposit ZnO/CDs dievaluasi dengan mendegradasi model polutan pewarna methylene blue dibawah iradiasi cahaya UV pada suhu ruang. Kemampuan fotodegradasi yang tinggi dari nanokomposist ZnO/CDs didemonstrasikan dengan membandingkannya dengan partikel ZnO yang disiapkan pada kondisi percobaan fotokatalisis yang sama. Hasil percobaan menunjukkan bahwa penambahan CDs pada ZnO dapat meningkatkan laju degradasi larutan Methylene blue sekitar 9 kali lipat dibandingkan dengan konstanta laju degradasi larutan Methylene blue tanpa fotokatalis.
