Development of Gold Nanoparticle-Doped Activated Carbon Sorbent for Elemental Mercury

The control of mercury (Hg) from coal-fired power plants by adsorption in solid sorbents is an attractive way to reduce Hg emissions. In this study, a commercial activated carbon (Norit RB3) was impregnated with gold nanoparticles for the retention of Hg in the gas phase, with the intention to explo...
