Two Cu-Co and Co3O4 oxides were synthesized by the conventional sol-gel auto-combustion and their physical-chemical properties were characterized by XRD, FTIR, SEM, TPR and XPS. The XRD results indicated that copper-cobalt oxide appeared in a mixture form of Cu0.15Co2.85O4 spinel and CuO phases, whereas the cobalt oxide exhibited in the pure form of Co3O4 spinel. The FTIR approved the formation...

Silica gel loaded with saturated Al(N03)3. 10. H20 solution proved to be an efficient absorbent for the elimination of the interference of fluorine in the microdetermination of carbon and hydrogen in organofluorine compounds. The reagent is cheap, readily available and easily prepared. Three grams are sufficient for 25 determinations. Samples are burnt in a flow of oxygen using the rapid straig...

A parallel solution combustion synthesis technique was developed for combinatorial materials studies. The vigorous combustion reactions were successfully limited in the microreactors by using a substrate-net-mask microreactor system and the lowest adoptable furnace temperature. Using this technique, a luminescent materials library of Y3Al5O12/Tb(chi) was synthesized with the aid of an ink-jet d...

Cerium orthovanadate nanoparticles (CeVO4 NPs) were fabricated using urea-assisted facile sol-gel auto combustion method. X-ray diffraction (XRD) pattern revealed the crystal planes and size of synthesized CeVO4 NPs. The morphological shape and the crystalline nature of the NPs were examined by field emission scanning electron microscopy (FESEM). Energy-dispersive X-ray spectroscopy (EDX) affir...

Carbon materials derived from biomass are drawing increasing attention due to its advantages in economical as well ecological production. Among the resources be utilized for that purpose, lignin possesses unique characteristics: it is available bulk quantity a low-value by-product pulp and paper industries chemical structure based on complex aromatic networks provides excellent precursor grahit...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...
