“…6.8% chemisorbed water molecules were present in AC. The second major weight loss around 400°C, is associated with the degradation of propylamine group (Vandarkuzhali and Radha 2013). Above 750°C the system exhibited 60.2% as a weight residue remained.…”

“…Reductive decontamination of nitrophenol was done with the aid of Mg-AC . Other authors (Vandarkuzhali and Radha 2013;Liu et al 2016;Celebi et al 2016) also reported about the catalytic activity of metal nanoparticle immobilized AC. By thorough literature survey, it was found that the catalyst was deactivated fast due to leach of metal nanoparticles into the reaction medium in the subsequent runs and hence it leads to the low % of aimed product.…”

A novel Ni complexed aminoclay (AC) catalyst was prepared by complexation method followed by reduction reaction. Various analytical techniques such as FTIR spectroscopy, UV-visible spectroscopy, DSC, TGA, SEM, HRTEM, EDX, XPS and WCA measurement are used to characterize the synthesized material. The AC-Ni catalyst system exhibited improved thermal stability and fiber-like morphology. The XPS results declared the formation of Ni nanoparticles. Thus, synthesized catalyst was tested towards the Schiff base formation reaction between various bio-medical polymers and aniline under air atmosphere at 85°C for 24 h. The catalytic activity of the catalyst was studied by varying the % weight loading of the AC-Ni system towards the Schiff base formation. The Schiff base formation was quantitatively calculated by the 1 H-NMR spectroscopy. While increasing the % weight loading of the AC-Ni catalyst, the % yield of Schiff base was also increased. The k app and Ti values were determined for the reduction of indole and a-terpineol in the presence of AC-Ni catalyst system. The experimental results were compared with the literature report.

“…Hence, the reduction of NiP using various catalyst systems is the only way to reduce the pollution caused by the NiP. Currently, various catalyst systems such as iron niobate [6], hydroxyapatite [7], Au nanoparticles (NP) [8], Au-SiO 2 [9], layered double hydroxides (LDH) [10], TiO 2 [11], Al 2 O 3 [12], Pd-Ag [13], AC-Ag [14], Au-CeO 2 [15], aminoclay-Fe NP [16], Clay-Pt [17], Fe 3 O 4 [18], Ni-Se [19] and Ni-P [20] are used for the reduction of NiP. Through study of the literature, any report based on the Cu and Al nanoparticles as a catalyst for the reduction of NiP in the presence of NaBH 4 is not found.…”

Cu and Al nanoparticles were prepared using a simple chemical etching method followed by a chemical reduction method. The synthesized metal nanoparticles were characterized by Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), electron-dispersive (EDX) spectrum and water contact angle (WCA) measurements. The application of Cu and Al nanoparticles was tested towards the catalytic reduction of 4-nitrophenol (NiP), hexavalent chromium {Cr(VI)} and rhodamine 6G (R6G) dye in the presence sodiumborohydride (NaBH 4) as a reducing agent. From the UV-visible spectrum, the reduction rate constant (k app) and the induction time (T i) were determined and compared critically. The HRTEM analysis confirmed the nanosize of Cu and Al prepared by a simple chemical etching process followed by the chemical reduction method.
