1. A method for the in situ synthesis of MOFs, COFs, or ZIFs, onto and within a porous substrate comprising: contacting the porous substrate with a first solution and a second solution, wherein the first and the second solutions are capable of forming the said MOFs, COFs, or ZIFs, and wherein the ratio of in situ synthesized adsorbent to bare substrate is in the range of 0.1 to 6 times by weight of the in situ synthesized adsorbent to the bare substrate.
