Activated carbon supported with silver nanoparticles was synthesized in supercritical water condition at 673 K and 30.0 MPa in a batch reactor. The reaction time was 30 min with concentration of silver acetate solution at 0.02 M. Synthesized activated carbon-Ag particles were characterized by X-ray diffraction, Fourier transformation confirmed infrared spectroscopy and scanning electron microscopy. X-ray diffraction measurement indicated the presence of metallic silver. Fourier transformation infrared spectroscopy traces of primary activated carbon, activated carbon treated in supercritical water condition and synthesized activated carbon-Ag showed slight shift near 1629 cm-1 due to silver bonding to activated carbon via carbonyl and carboxyl groups. There was also observed chain-like structure of activated carbon-Ag with size of around 100 nm when sScanned by electron microscopy.
