    Biomass from the agriculture wastes can be transformed to valuable carbon support through hydrothermal carbonization (HTC). In this study, the biomass was hydrothermally treated at 200°C for 24 h in the presence of transition metals as catalysts. Various types of metal-salt solutions comprising of Cu(NO<inf>3</inf>)<inf>2</inf>, Cd(NO<inf>3</inf>)<inf>2</inf>, Fe(NO<inf>3</inf>)<inf>3</inf>, Ni(NO<inf>3</inf>)<inf>2</inf> and Ba(NO<inf>3</inf>)<inf>2</inf> with a concentration of 5 wt% during HTC, were investigated to study their effects on surface functional characteristics and morphological appearance of the synthesized carbons, which were subsequently characterized using FT-IR, and SEM analyses. Furthermore, the remaining metal particles on the synthesized carbon surface were found to be effective for catalytic applications. Thus, HTC of agriculture by-products in combination with the addition of transition metals would be an effective technique to prepare catalysts in a facile way.
