THE ROLE OF N-DOPING TO THE PORE CHARACTERISTICS OF ACTIVATED CARBON FROM VETIVER ROOT DISTILLATION WASTE

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