Enriched characteristics like porosity, stability and specific surface area assist TiO2 to find extensive applications in photocatalysis, dye sensitized solar cell, and sensors. TiO2 semiconductor was prepared using titanyl acetylacetonate and characterized by XRD, FTIR, Raman, UV-Vis, FESEM, EDX, and DLS. XRD result confirmed the tetragonal structured anatase TiO2 semiconductor. Scherrer formula is used to […]
Aluminophosphate and metal incorporated aluminophosphates have been synthesized at ice-cold temperature by simple co-precipitation method in the absence of a templating agent. Surface and bulk properties of synthesized materials were studied by different characterization techniques. The materials were found to be X-ray amorphous. N2 adsorption-desorption studies exhibited the existence of microporous structure and uniform narrow […]
Catalytic oxidation of D-glucose to D-gluconic acid derivative with H2O2 has been studied using non-noble Cobalt supported catalyst. The catalysts were synthesized using the scalable incipient wetness impregnation method of Co/Al2O3 and Co/TS1. The catalysts have been characterized by TGA, XRD, FESEM-EDX, BET, FTIR, and Hammett test. The oxidation of the D-glucose into D-gluconic acid […]
A green and efficient trifluoroacetate-bonded polyethylene graphene oxide composite was utilized in this research to prepare benzimidazoles with good to excellent yield under a solvent-free condition. The trifluoroacetate-bonded polyethylene graphene oxide composite was constructed by polyethylene/diethylenetriamine-functionalized graphene oxide composite bonded by 2-aminothiazole and CF3COOHmoieties. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, field emission […]
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 […]
