- [<b>ABSTRAK</b><br> Komposit Multi-Walled Carbon Nanotubes (MWCNT)/Titania telah disintesis untuk mendegradasi fenol sebagai model limbah industri farmasi. Sintesis komposit MWCNT/Titania dilakukan dengan pretreatment asam kepada MWCNT, pengaturan pH larutan dan metode ultrasonikasi. Sampel dikarakterisasi dengan FE-SEM/EDX, XRD dan UV-Vis DRS. Hasil karakterisasi FE-SEM/EDX, XRD dan UV-Vis DRS menunjukkan bentuk komposit yang homogen dengan kristal fasa anatase dan rutile yang berukuran 14 nm dan 15 nm serta tingkat celah energi sebesar 3,05 eV. pH pengkompositan MWCNT/Titania optimum untuk mendegradasi fenol adalah pH 3. Komposisi MWCNT optimum dengan aktivitas fotokatalis tinggi yaitu 3% berat. Komposit MWCNT/TiO2 mampu mendegradasi senyawa fenol hingga 100% setelah 4 jam pengujian. <hr> <b>ABSTRACT</b><br> Multi-Walled Carbon Nanotubes (MWCNT)/Titania composite have been synthesized to degrade phenol as a model of the pharmaceutical industry waste.
