Reusable and Flexible Heterogeneous Catalyst for Reduction of TNT by Pd Nanocube Decorated ZnO Nanolayers onto Electrospun Polymeric Nanofibers

摘要: An effective method for the fabrication of well designed nanocomposite catalytic reduction 2,4,6-trinitrotoluene (TNT) was developed. Here, cubic palladium (Pd) nanoparticles were utilized enhancing interface properties, attachment quality, yield and stability after catalysis reactions. Ligand controlled facet growth by Br- anions during thermal decomposition palladium-precursor resulted with shaped average ∼13 nm nanocubes (Pd NC). The anisotropic Pd NC to decorate surface zinc oxide (ZnO) nanolayers deposited atomic layer deposition (ALD) technique on electrospun polyacrylonitrile (PAN) nanofibers. Due polymeric nature PAN nanofibers, decorated nanoweb is highly flexible has a high area. For sustainable decoration ZnO surfaces coated anchor points formed functional thiol groups which can facilitate surface. -OH alkyl obtained via sol-gel reactions positioned providing better between cannot be pristine Additionally, due increased interaction, geometrical positioning fibers intermediate complex formation soft-soft provided enhanced TNT in aqueous medium.
