FeO/PANI/CuI as a sustainable heterogeneous nanocatalyst for A coupling.

The prepared copper iodide nanoparticles were impregnated on the support of ferrite nanoparticles functionalized with polyaniline, resulting in a magnetically recoverable heterogeneous nanocomposite. The activity of the prepared nanocomposite was investigated in the synthesis of propargylamine derivatives A coupling under mild conditions. Techniques such as FESEM, EDAX, XRD, XPS, TEM, BET and FTIR were used to characterize the effective and unique heterogeneous FeO/PANI/CuI nanocomposite developed in this work.

MoS intercalated NiFeTi LDH as an efficient and selective adsorbent for elimination of heavy metals.

The enormous increase of heavy metal pollution has led to a rise in demand for synthesizing efficient and stable adsorbents for its treatment. Therefore, we have designed a novel adsorbent by introducing (MoS) moieties within the layers of NiFeTi LDH-NO, an ion exchange mechanism, as a stable and efficient adsorbent to deal with the increasing water pollution due to heavy metals. Characterization techniques such as XRD, FTIR, TGA, SEM, TEM, and Raman spectroscopy were used to confirm the formation of (MoS) intercalated NiFeTi LDH and structural changes after the adsorption process.
