This work studied the effect of nitrogen functional group modification on activated carbon synthesized from vetiver root waste on pores development. Synthesis of activated carbon was carried out by hydrothermal carbonization of vetiver root waste at a temperature of 225 ⁰C for 18 hours followed by chemical activation using K2FeO4as activated agent in a furnace at temperature of 800 ⁰C for 2 hours with nitrogen atmosphere flowed at a rate of 100 mL/minute. Urea was used as a nitrogen source. The variation of urea concentration was 1:0 (AC0–800), 1:3 (AC3–800) and 1:5 (AC5–800). The results showed that these activated carbons have mesoporous characteristics with the largest Brunauer Emmett Teller (SBET) surface area of 552.90 m2g-1 and average pore width 3,43 nm. The presence of nitrogen functional group was observed in the Fourier Transform Infrared Spectrometer analysis. Synthesis of activated carbon from vetiver root waste with an addition of urea is the newest method to produce mesoporous activated carbon for electrode and  support catalyst purposes.

Increased Activity

Pd on N doped activated carbon exhibited increased activity and stability in 4-CBA hydrogenation relative to Pd catalysts without N doping. Higher dispersion of Pd0 and facile activation of H2 accounted for the better activity of Pd/NC.

In this study, a portable and disposable paper-based microbial fuel cell (MFC) was fabricated. The MFC was powered by Rhodopseudomonas palustris bacteria (R. palustris). An activated carbon sheet-based anode pre-loaded organic matter (starch) and R. palustris was used. By using starch in the anode, R. palustris-loaded on the anode could be preserved for a long time in dry conditions. The MFC could generate electricity on-demand activated by adding water to the anode. The activated carbon sheet anode was treated by UV-ozone treatment to remove impurities and to improve its hydrophilicity before being loaded with R. palustris. The developed MFC could generate the maximum power density of 0.9 μW/cm2 and could be preserved for long-term usage with little performance degradation (10% after four weeks).
