An international collaborative team with members from PolyU and Northwestern University (USA), and Dr Ma Kaikai, Assistant Professor from SFT as a core member, has successfully developed catalytic zirconium (Zr)- metal-organic framework (MOF) nanozyme coated cellulose nanofibre aerogel that has exceptional detoxification properties against the ultra-toxic organophosphorus toxin. The novel fibrous aerogel composites, which have high MOF loadings and a unique hierarchical porosity structure, allow for efficient access to catalytic active sites.
The resulting fibrous Zr-MOF nanozyme aerogel composites represent a significant leap forward in environmentally-friendly sustainable forms of protection against toxins. Their ability to continuously hydrolyse and detoxify organophosphorus-based nerve agent simulants and pesticides from contaminated water highlight their potential for real-world applications.
With a simple synthesis process and optimal detoxification performance, these nanocomposites are a promising solution to eliminate toxic agents in a variety of settings. This development marks a significant milestone in safeguarding both the environment and human health, thus paving the way for a more sustainable future. The work is published in a top-tier journal, Advanced Materials.
