3D metal–organic frameworks (MOFs) can be appropriate templates for the fabrication of nanomaterials due to they have active sites exposed on channel or surface, which thus provide them with improved catalytic performance. In this study, a cobalt-based MOF [Co(H2bpta)]n (Co-MOF), where H4bpta denotes 2,2′,4,4′-biphenyltetracarboxylic acid, has been constructed use ligand high carbon content. On...

This paper reports on synthesis of a magnetic adsorbent for wastewater treatment purposes. In this regard, platanus orientalis waste leaves were chosen as a cheap material for preparing the magnetic adsorbent by loading magnetite nanoparticles on it. The synthesized adsorbent was characterized using scanning electron microscope and X-ray diffractometer. Then, it was used for magnetic solid phas...

In this research we first synthesized MgFe2O4 nanostructures via hydrothermal method using (Mg(NO₃)₂.6H₂O) and (Fe(NO₃)₃.9H₂O). The influence of concentration, surfactant, precipitating agent and temperature on the particle size and magnetic properties of the synthesised nanoparticles were examined. Then MgFe2O4-Ag nanocomposites were prepared by a simple chemical precipitation. The structural ...

The present work aims to investigate the effect of parameters laser machining process and line angle injection direction sample plastics on electrical resistance Polymethyl Methyl Methacrylate (PMMA)/Multi-Wall Carbon Nanotubes (MWCNT) Nano-composite. was performed samples considering a combination power, feed rate, with respect melted flow parameters. According obtained results from magnetic p...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

in the present study, removal of dibenzothiophene (dbt) from model oil (n-hexane) was investigated using magnetic activated carbon (mac) nano-composite adsorbent. the synthesized nano-composite was characterized by ft-ir, fe-sem, bet and vsm techniques. the mac nano-composite exhibited a nearly superparamagnetic property with a saturation magnetization (ms) of 29.2 emu g-1, which made it desira...

sio2-coated cobalt ferrite (cofe2o4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of cofe2o4 nanoparticles in co-precipitation. the effects of sio2coating on the magnetic properties of cofe2o4 nanoparticles were investigated. the structural, morphological and magnetic properties of as-prepared sample were characterization by x-ray diffraction (xrd), f...

tio2 photo catalyst was prepared in presence of nano sio2 and hydroxy propyl cellulose (hpc) by sol gel method with titanium tetra isopropoxide (ttip) as titanium precursor. additional effect of hpc in preparation of nano catalyst, and photo catalyst properties measured and characterized by ft-ir, ft-raman and sem. the catalyst size and structural properties of the film were determined by .-ray...
