Colloidal stability of phytosynthesised gold nanoparticles and their catalytic effects for nerve agent degradation
Original language description
Herein, Tilia sp. bract leachate was used as the reducing agent for Au nanoparticles (Au NPs) phytosynthesis. The colloidal properties of the prepared Au NPs were determined to confirm their stability over time, and the NPs were then used as active catalysts in soman nerve agent degradation. The Au NPs characterisation, reproducibility and stability studies were performed under transmission electron microscopy, ultraviolet visible spectroscopy and with ζ-potential measurements. The reaction kinetics was detected by gas chromatography coupled with mass spectrometry detector and solid-phase micro-extraction to confirm the Au NPs applicability in soman hydrolysis. The ‘green’ phytosynthetic formation of colloidal crystalline Au NPs with dominant quasi-spherical shape and 55 ± 10 nm diameter was successfully achieved, and there were no significant differences in morphology, ζ-potential or absorbance values observed during the 5-week period. This verified the prepared colloids’ long-term stability. The soman nerve agent was degraded to non-toxic substances within 24 h, with 0.2156 h−1 reaction rate constant. These results confirmed bio-nanotechnology’s great potential in preparation of stable and functional nanocatalysts for degradation of hazardous substances, including chemical warfare agents.
