Abstract

Nanokomposit TiO2/karbon telah disintesis menggunakan metode solid state reaction. Sintesis dilakukan pada variasi persentase massa karbon 20, 40, 60, 80 dan 100%. Nanokomposit dikalsinasi pada suhu 400oC dan kemudian dikarakterisasi menggunakan SEM-EDS and LCR meter. Profil SEM menunjukkan TiO2/karbon tersusun oleh partikel-partikel yang kecil hampir mendekati skala nanometer. Ukuran partikel terkecil dimiliki oleh sampel dengan persentase massa karbon 60%, yaitu berkisar 158 nm. Konduktivitas listrik sampel untuk masing-masing persentase karbon secara berurutan adalah 2,14×10-3 S/m; 8,47×10-3 S/m; 1,29×10-2 S/m; 5,92×10-3 S/m dan 1,82×10-3 S/m. Konduktivitas listrik TiO2/karbon tertinggi dimiliki sampel dengan persentase karbon 60% yaitu 1,29×10-2 S/m. Konduktivitas TiO2/karbon lebih tinggi dibandingkan TiO2 yaitu 6,03×10-3 S/m.
