In this work, Activated carbon was synthesized from Rice Husks (RH) using the chemical activation method with KOH as the chemical activating reagent. The Pt-Ru metals were deposited onto activated RHs (A-RHs) by chemical reduction method. The characteristics of Pt-Ru RH catalysts were determined by specific surface area and pore size analyzer, X-ray diffraction (XRD), transmission electron microscopy (TEM). The textural properties of A-RH were investigated by N2/77 K adsorption isotherms using Brunauer-Emmett-Teller (BET) equation and Barret-Joyner-Halenda (BJH) method. The electrochemical properties of Pt-Ru/RHs catalysts were also analyzed by cyclic voltammetry (CV). |
