This work presents a simple effective strategy to synthesize N-doped and shell-controlled carbon nanocages through package baking approach. A green approach core-shell ZIF-8@PTZ nanoparticles involves zinc contained ZIF-8 core wrapped by N-enriched polytriazine (PTZ). Synthesized are calcinated further sublime PTZ shell washed HCl, leaving porous structure. At the meantime, hollow cavities were...

TiO2/ZrO2 nanocomposite was obtained by the sonochemical technique. In this method, two separate gels containing zirconium and titanium were prepared and mixed together. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4. The precursor titanium tetra isopropoxide (TTIP) dissolved in isopropanol. Mixing of Titanium and Zirconium gels was resulted in a yellow TiO2/ZrO2 ...

In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibr...

In this work firstly ZnO nanoparticles were synthesized via a simple precipitation method. At the second step titanium dioxide and silicon dioxide shell were synthesized on the core. For preparation ZnO-TiO2-SiO2 the sol product was calcinated at 500 ºC for 2h. Properties of the product were examined by X-raydiffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform inf...

The development of superior low-temperature catalytic performance and inexpensive catalysts for the removal volatile organic compounds (VOCs) is crucial their industrial application. Herein, CuO/Ce0.6Zr0.4O2 calcinated at different temperatures (Cu/CZ-X, X represented calcination temperature) were prepared used to eliminate toluene. It can be found that Cu/CZ-550 presented highest activity, wit...

In the present work, hematite (α-Fe2O3) nanoparticles (NPs) were synthesized by using a simple and facile green synthesis Hibiscus plant extract. The used solution is composed of extract 0.1 M iron chloride mixture. are grown at ambient temperature. prepared morphology, structure composition characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscop...

Eutrophication caused by excessive discharging of phosphorus is a global water pollution problem. To further improve the adsorption capacity natural palygorskite and easy separation from liquid, magnetic thermal modified nanocomposite (MTPG) was firstly fabricated then characterized XRD SEM-EDS. The characterization results showed Fe3O4 in nano-diameters prosperously immobilized on surface (TPG...

This study synthesised eggshell waste, an agricultural by-product, into a calcinated porous material modified by salicylic acid as new and effective adsorbent for remediation of Cu(II) from aqueous solution. The impregnation onto the surface egg-shell improved adsorption property eggshell. Furthermore, it was found that acid-modified egg-shell; (SAL-E) has highly developed functionalised rich p...

High-temperature superconductor YBa2Cu3O7−δ (YBCO) nanopowders were synthesized by the citrate-gel route, which is a modification of the sol-gel method. The fine powders were calcinated at 860 and 900 °C. They were of small size, in the range of 30–35 nm. X-ray diffraction (XRD) patterns verified production of the orthorhombic superconducting phase in all samples. Measuring the magnetic propert...
