Abstract
Telah dilakukan penelitian sintesis dan karakterisasi CNT (Carbon Nanotube) dengan doping logam kobalt. Penelitian ini bertujuan untuk menentukan karakter CNT sebelum dan setelah didoping dengan variasi konsentrasi logam 10%, 20%, 30%, 40% dan 50%. Metode yang digunakan pada penelitian ini adalah impregnasi basah yang meliputi perendaman pada larutan logam dan kalsinasi. Hasil impregnasi dianalisis menggunakan Fourier Transform-Infra Red (FT-IR), GSA (Gas Sorption Analysis), Scanning Electron Microscopy (SEM) dan Energy Dispersive X-Ray Spectroscopy (EDS). Analisis FT-IR menunjukkan adanya vibrasi ulur dari ikatan Co-C dan Co-O.  Hasil GSA menunjukkan bahwa CNT loading 30% mempunyai luas permukaan tertinggi yaitu 69,192 m2/g. Hasil SEM-EDS menunjukkan bahwa morfologi permukaan dinding CNT ditutupi aggregat-aggregat kobalt. Pada hasil EDS fraksi kobalt dihasilkan adalah 1,96 % yang nilainya tidak jauh berbeda dari fraksi Fe yaitu 1,49%. Hal ini menunjukkan bahwa CNT doping logam Co menggunakan metode impregnasi basah tidak efektif.
