Abstract

The development of catalytic materials with high catalytic activity and stability with a low noble metal loading on environmentally friendly and inexpensive supports would be a promising strategy. Based on this principle, we have designed an MS 3Å/Cu0 nanocatalyst by stabilizing Cu nanoparticles on a commercial zeolite of type LTA-3Å using a simple and easy method. The morphology and structure of MS 3Å/Cu0 material were fully characterized by XRD, FT-IR, FE-SEM, XPS and TEM. The results obtained clearly show the formation of copper nanoparticles on the surface of the zeolite. The universality of the catalyst towards the reduction of various organic pollutants such as 4-nitrophenol (4-NP), 2-nitrophenol (2-NP), 2-nitroaniline (2-NA), 4-Fluoro-2-nitroaniline (4-F-2-NA), 4-fluoro-3-nitroaniline (4-F-3-NA) and methylene blue (MB) in the presence of NaBH4 was evaluated. The MS 3Å/Cu0 material exhibits very efficient and rapid catalytic reduction activity at room temperature.
