Adsorbent for adsorbing virus and/or bacterium, carbon/polymer composite and adsorbent sheet

A method, comprising:

• providing a carbon/polymer composite, wherein the carbon/polymer composite comprises:
• a porous carbonaceous material comprising pores having diameters in a range from 1×10−9 m to 5×10−7 m, wherein the porous carbonaceous material has a specific surface area of 10 m2/g or more as measured by a nitrogen BET method, a total pore volume of 0.1 cm3/g or more as determined by Non Localized Density Functional Theory, at least one peak in a pore diameter distribution in a range from 3 nm to 20 nm as determined by Non Localized Density Functional Theory, and a ratio of the volume of pores with diameters in the range from 3 nm to 20 nm to the total pore volume of 0.2 or more;
• and
• a binder;
• and
• adsorbing a virus and/or a bacterium to the carbon/polymer composite.

A method, comprising:

• providing an adsorbent sheet, wherein the adsorbent sheet comprises:
• a porous carbonaceous material comprising pores having diameters in a range from 1×10−9 m to 5×10−7 m, wherein the porous carbonaceous material has a specific surface area of 10 m2/g or more as measured by a nitrogen BET method, a total pore volume of 0.1 cm3/g or more as determined by Non Localized Density Functional Theory, at least one peak in a pore diameter distribution in a range from 3 nm to 20 nm as determined by Non Localized Density Functional Theory, and a ratio of the volume of pores with diameters in the range from 3 nm to 20 nm to the total pore volume of 0.2 or more;
• and
• a support member;
• and
• adsorbing a virus and/or a bacterium to the adsorbent sheet.
