removal of heavy metal by nickel oxide nano powder
in this study metal oxide nano powder namely nio nanopowder was prepared .the producedmetal oxide was characterized and used as potential adsorbent for the removal of pb and zn from aqueoussolution. the rate of uptake of the pb and zn are rapid in the beginning and the time required for equilibrium adsorption is 120 min .the time of equilibrium as well as time required to achieve a definite fra...
متن کاملSynthesis – structure correlations of manganese – cobalt mixed metal oxide nanoparticles
Mixed metal oxides in the nanoscale are of great interest for many aspects of energy related research topics as water splitting, fuel cells and battery technology. The development of scalable, cost-efficient and robust synthetic routes toward well-defined solid state structures is a major objective in this field. While monometallic oxides have been studied in much detail, reliable synthetic rec...
متن کاملZirconium Oxide Mixed Tantalum Oxide High-K Gate Dielectric Films for Metal-Oxide-Semiconductor (MOS) Devices
Hafnium oxide mixed tantalum oxide (HTO) and Zirconium oxide mixed tantalum oxide (ZTO) layers were deposited on chemically cleaned p-Si substrate using RF magnetron sputtering technique. The oxide/Si stacks were annealed in oxygen for 30 minutes at 400 °C as on initial investigation. Both composition and structural properties were absolutely interesting to move further for electrical measureme...
متن کاملTuning Ferritin's band gap through mixed metal oxide nanoparticle formation.
This study uses the formation of a mixed metal oxide inside ferritin to tune the band gap energy of the ferritin mineral. The mixed metal oxide is composed of both Co and Mn, and is formed by reacting aqueous Co2+ with [Formula: see text] in the presence of apoferritin. Altering the ratio between the two reactants allowed for controlled tuning of the band gap energies. All minerals formed were ...
متن کاملComposition Space Diagrams for Mixed Transition Metal Oxide Fluorides.
Composition space diagrams have been used to study phase stability of mixed transition metal oxide fluorides synthesized by hydrothermal reaction of the metal oxides in (HF)(x)().pyridine/H(2)O/pyridine solution (150 degrees C, autogenous pressure). The combination of early (Ti, Zr, Hf, Nb, Ta, Mo, W) and late (Cu, Cd, Zn) transition metals and the effects of varying the mole ratios of the meta...
