- Abstract
In this work, we developed cellulose acetate-stabilized zero-valent Cu nanoparticles by reducing metal cations using NaBH4 in a straightforward chemical process. Energy Dispersive X-ray Spectroscopy (EDS) was used for elemental analysis, Fourier-Transform Infrared Spectroscopy (FTIR) was used to identify the functional groups responsible for nanoparticle stabilization, and Field-Emission Scanning Electron Microscopy (FESEM) was used to characterize the morphology of the synthesized nanoparticles. Using para nitrophenol as a model pollutant, the effectiveness of the synthesized catalyst was evaluated. By introducing 15 mg of the catalyst, 2.5 mL of 0.1 mM PNP was completely reduced in 15 min, while NaBH4 served as a reducing agent, resulting in 94% reduction efficiency. To clarify the reduction mechanism, several kinetics models were used. The greatest R2 value (0.8099) was found in both the first and pseudo-first-order kinetics, with a rate constant of 0.1947. The second-order reaction had the highest rate constant (0.7407) and the lowest R2 value (0.6201), showing that the first-order kinetics model provided the best fit. Regression and analysis of variance (ANOVA) tests were also carried out to validate the reaction procedure. Moreover, the recyclability of the synthesized catalyst has been also checked showing that it is very reliable. The results of this investigation indicate that the synthesized CA@Cu can be used to effectively reduce and convert PNP to amino phenol.
