“… 18 Some successful studies using HAP as a support for metal nanoparticles for application in the reduction of 4-NP were found in the literature. For instance, Bahadorikhalili et al 19 successfully synthesized Ag NP-decorated thiourea-functionalized magnetic HAP that can reduce 4-NP with a rate constant k = 0.025 s –1 . Das et al 20 decorated HAP with Ag NPs by a facile green method for the reduction of 4-NP and organic dyes.…”

Metallic copper nanoparticle (Cu NP)-doped 1D hydroxyapatite was synthesized using a simple chemical reduction method. To describe the structure and composition of the Cu/HAP nanocomposites, physicochemical techniques such as X-ray diffraction, Fourier transform infrared spectroscopy, inductively coupled plasma, N 2 adsorption–desorption, X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy were used. The TEM scan of the Cu/HAP nanocomposite revealed a rod-like shape with 308 nm length and 117 nm width on average. The catalytic activity of Cu/HAP nanocomposites for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in the presence of NaBH 4 has been thoroughly investigated. The 0.7% Cu/HAP nanocomposite was shown to have superior catalytic activity than the other nanocomposites, converting 4-NP to 4-AP in ∼1 min with good recyclability. Moreover, this nanocomposite showed excellent catalytic performance in the organic dye reduction such as Congo red and acriflavine hydrochloride dyes. The high dispersion of Cu NPs on HAP support, the high specific surface area, and the small Cu particles contributed to its remarkable catalytic performance.

A novel catalyst is designed and synthesized based on immobilization of copper onto modified magnetic nanoparticles. The catalyst was characterized by several characterization techniques. The catalyst was applied for the synthesis of a novel series of heterocyclic scaffold containing a 1,4‐benzodiazepine fused with a 1,2,3‐triazole ring and a quinazolin‐11(9H)‐one skeleton. The method is based on the direct synthesis of quinazolin‐11(9H)‐one ring by the reaction of isatoic anhydride (or anthranilic acid) and propargylamine, and an aldehyde, containing a leaving group on its aromatic ring. The reaction contains an in situ sequential click reaction of azide group with terminal alkyne and subsequent N‐arylation reaction to afford the final products. The method benefits various advantages, such as regioselectivity and high yield of the products. The reusability of the catalyst was evaluated and the results showed that the catalyst is highly reusable in 10 sequential reactions.

“…Nitroarene compounds, which can be said to be relatively rare in nature, have entered the environment and caused pollution through human activities such as agriculture, dyeing, and some factories. Among them, nitrophenols are often known as toxic compounds of environment pollutants that they can easily affect life by contaminating sewage and food chain system 24,25 . In the environmental point of view, the synthesis of amines through the nitro-reduction process is one of the motivating reactions 15,[26][27][28] .…”

In the present study, a natural-based heterogeneous catalyst is synthesized. For this purpose, nano-hydroxyapatite (n-HA) is prepared, silica-modified and functionalized with phthalimide. Finally, Ag2+ was immobilized onto n-HA/Si-PA-SC and reduced to Ag nanoparticles by Bellis perennis flowers extract. n-HA/Si-PA-SC@Ag characterized by TGA, FTIR, SEM/EDX, XRD, TEM, BET and ICP-AES techniques. Moreover, metal–ligand interactions in n-HA/Si-PA-SC@Ag complex models were assessed to make a quantitative representation for the immobilization behavior of Ag NPs on the surface of n-HA/Si-PA-SC through quantum chemistry computations. Furthermore, the performance of n-HA/Si-PA-SC@Ag was studied in the nitroarene, methylene blue and congo red reductions. Finally, the recyclability study as well as Ag-leaching verified that, n-HA/Si-PA-SC@Ag was stable and reused-up to four times without losing its activity.
