Abstract: A porous composite adsorbent is provided to increase treatment capability of harmful gases, exhibit antibacterial properties of silver, prevent an existing problem that the harmful gases are desorbed again due to weak adsorptive power, and prolong the short replacement cycle of the adsorbent, a method of preparing the porous composite adsorbent is provided, and a filter using the porous composite adsorbent is provided. A porous composite adsorbent comprises a porous adsorbent body formed by doping and modifying an effective metal and an antibacterial porous adsorbent body doped with silver. A method of preparing a porous composite adsorbent comprises the steps of: (a) adding a porous adsorbent body and a porous adsorbent body having an oxidative functional group obtained treating the porous adsorbent body with an acid into a metal precursor solution to dope and modify the porous adsorbent body and the porous adsorbent body having an oxidative functional group with metal oxides, and drying and firing the metal oxide-doped and modified porous adsorbent bodies to prepare a porous adsorbent body formed by doping and modifying an effective metal; (b) dissolving an aqueous solution in which a silver(Ag) compound is mixed with alcohol into a polymer mixed solution, and reducing silver with an organic acid to prepare a nano-dispersion, dissolving the nano-dispersion into distilled water, mixing the dissolved solution with an acid treated porous adsorbent body, and firing the mixture to prepare an antibacterial porous adsorbent body doped with silver; and (c) mixing adsorbent bodies of the step(a) and the step(b) in a mixer to form a porous composite adsorbent. Further, the porous adsorbent body is one or more selected from activated carbon, diatomite, zeolite, silica gel and bentonite.
