1. A catalyst composition comprising a copolymer of a first polymer and a second polymer;
wherein the first polymer includes an alkyl (meth)acrylate polymer, and the alkyl is any one selected from the group consisting of methyl, ethyl, and propyl, and the second polymer is a branched polyethylenimine (BPEI) or linear polyethylenimine (LPEI), and
a zirconium (Zr) metal-organic framework selected from the group consisting of UiO-66, UiO-67, PCN-545, and NU-1000,
wherein the metal-organic framework has chemical warfare agent (CWA) degradation ability that includes liquid- or gas-phase detoxification, and
the copolymer is formed by a coupling reaction of the first and the second polymers.
