Abstract

Ananas comosus leaf is one of the agricultural wastes that has resulted in environmental pollution. Recently, this waste has been explored for its potential in synthesising environmentally friendly metallic nanoparticles. Ananas comosus leaf extract has been proposed as a viable and economical option for reducing, capping, and stabilising agents in synthesising copper nanoparticles. This study used Ananas comosus leaf extract and copper sulphate as precursor materials to produce copper nanoparticles in the green synthesis process. The results show that the absorption spectra in the UV-visible range exhibit a peak absorption value at a wavelength of 238 nm. Fourier Transform Infrared analysis revealed the presence of bioactive compounds in the Ananas comosus leaf extract, which are responsible for reducing Cu²⁺ ions to Cu⁰ nanoparticles. The Field Emission Scanning Electron Microscope analysis indicated that the copper nanoparticles have a face-centred cubic crystal structure, which is significant for innovative nanoparticle applications. The average particle size was determined to be 56.71 nm. X-ray diffraction analysis revealed peaks at 43.46°, 50.57°, and 74.23°, corresponding to the (111), (200), and (220) lattice planes, respectively, confirming the structural properties of the synthesised nanoparticles. Energy Dispersive X-ray examination found that the synthesised copper nanoparticles are primarily composed of copper, accounting for 95.24% of the total composition. The phytochemicals in the extract have been effectively utilised in the green synthesis of copper nanoparticles, demonstrating potential applications in medicine and agriculture.
