A tunable species removal media including a polymer-impregnated porous material with the introduction of heteroatoms into the porous material during the synthesis of the oxide support. The polymer can be poly(ethyleneimine) (PEI), the porous material a framework of silica nanoparticles, and the heteroatoms selected from Zr, Ti, Fe, Ce, Al, B, Ga, Co, Ca, P, and Ni. The media has a CO2 adsorption of greater than 0.19 mmol CO2/g when exposed to a 400 ppm CO2/Ar flow at a rate of 100 mL/min, and can also have a CO2 adsorption of greater than 0.65 mmol CO2/g when exposed to a 10% CO2/Ar flow at a rate of 100 mL/min. The media can have a heteroatom/Si molar ratio greater than or equal to 0.002.
