Senyawa aromatik dalam limbah cair industri seperti fenol dapat berkontribusi sebagai polutan yang tinggi toksisitas dan karsinogeniknya. Degradasi fenol dapat dilakukan dengan proses fotokatalisis yang dapat mengubah fenol menjadi senyawa yang tidak beracun dan ramah lingkungan. Kinerja fotokatalis titania (TiO2) ditingkatkan dengan menggunakan carbon nanotube sebagai doping pada titania. Untuk mengurangi aglomerasi carbon nanotube, permukaan carbon nanotube dimodifikasi dengan surfaktan. Tujuan penelitian ini adalah membuat komposit titania-carbon nanotube (surfaktan) dan mengevaluasi pengaruh konsentrasi awal fenol (10, 20, 30 ppm) terhadap efektivitas fotodegradasi fenol menggunakan komposit titania-carbon nanotube (surfaktan). Sintesis komposit titania–carbon nanotube (surfaktan) dilakukan dengan membentuk komposit antara TiO2 dan carbon nanotube yang telah dimodifikasi oleh surfaktan. Hasil komposit dikarakterisasi menggunakan SEM, FTIR, dan XRD. Fotodegradasi fenol dilakukan pada suhu degradasi 50ºC selama 4 jam di bawah sinar UV. Sampel diambil dalam rentang waktu yang sama dan konsentrasi akhir fenol setiap sampel dianalisa menggunakan Spektrofotometer UV-Vis. Efektivitas degradasi yang paling tinggi diperoleh pada konsentrasi awal 10 ppm yaitu sebesar 81%.
