Abstract
⺠Silver nano-particles were attached onto the surface of GAC for the simultaneous catalytic oxidation and adsorption reactions of formaldehyde. ⺠By the silver nano-particles, formaldehyde oxidation to carbon dioxide as expressed as pseudo-first-order. ⺠The nano-particle deposits reduced the available surface area of the GAC and blocked the openings of the micro-pores. ⺠The modified numerical model yielded an accurate prediction of the performance of the Ag-GAC. ⺠Depending on the surface coverage ratio, the factions of catalytic oxidation and the formaldehyde mass removed were proportionally changed.
