In this work, ZrO2/TiO2/ZnO ternary nanocomposites were prepared by the sol-gel technique. The Taguchi method with the L9 orthogonal array was utilized to optimize the experimental conditions for the preparation of nanocomposites. The design has four factors, and each factor has three levels. The design factors of this study were calcination temperature, the aging time, […]
In this research, design and synthesis of Fe3O4@APTES@MOF-199magnetic nanocatalyst nanoparticles as a novel, recyclable and heterogeneous catalyst was developed. The magnetic nanocatalyst was analyzed using various spectroscopic methods such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), powder X-ray diffraction (XRD), energy dispersive X‐ray (EDX), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM). The […]
A novel nanomagnetic material with a dimethylamino tag namely nano-Fe3O4@SiO2@R-NMe2 ([NFSRN]) was produced, and characterized by EDS, FT-IR, VSM, FE-SEM, XRD and TGA analyses. Then, it was applied as a highly effective and magnetically recyclable catalyst for the one-pot multi-component reaction of malononitrile, arylaldehydes and dimedone. Interestingly, in most entries, among the possible products which […]
Platinum–nickel electrocatalysts supported on the modified carbon paper (MCP) were prepared by electrodeposition. Here, various procedures were applied for the electrodeposition of nickel and platinum particles, separately or simultaneously, on the surface of the MCP as an anode electrode for glucose alkaline fuel cells. The establishment of the best procedure for this fabrication is the […]

This review papers aims to comprehensively address the various aspects of ionic liquids and supported ionic liquids, which constitute a significant branch within the expansive field of green catalyst. Specifically, it delves into the recent advancements made in this domain over the past three years for the synthesis of heterocyclic compounds. In the introduction section […]
Green synthesis of cupric oxide nanoparticles (CuO NPs) has been promoted as an environmentally-friendly, cost-effective and high yield method. The CuO NPs have been synthesized by reducing copper sulphate using an aqueous flower extract of Clitoria ternatea. The UV-visible peak observed at 251 nm confirmed the formation of CuO NPs. The optical bandgap energy value […]
The development of an appropriate kinetic model for cracking reactions is essential for simulation and process optimization. These results are to be potentially used for proper reactor design. The complexities of oil gas inlet combinations have led to an increase in the challenges while defining and depicting kinetics on an intrinsic scale. Hence, complicated chemical […]
A novel organic-inorganic hybrid nanomaterial namely nano-[SiO2@R-Im-SO3H][CF3COO] (NSRISC) was synthesized, and characterized using FT-IR, EDS, FE-SEM, TGA and XRD analyses. Thereafter, the solvent-free production of bis-coumarins (from aryl aldehydes and 4-hydroxycoumarin) and N,N′-alkylidene bisamides (from aryl aldehydes and benzamide) was catalyzed by NSRISC. Bis-coumarins were produced in 86-97% at 100 ºC, and bisamides were obtained […]
