Relationship between chemical bonding nature and electrochemical property of LiMn(sub 2)O(sub 4) spinel oxides with various particle sizes: "electrochemical grafting" concept

Article Abstract:

The electrochemical properties of LiMn(sub 2)O(sub 4) spinel oxides with various particle sizes are enhanced when the grafting process of Li(super +) ion is facilitated. The facilitation of the grafting process of Li(super +) ion is made possible by the reduction of synthetic temperature, which alters the surface properties of the spinel oxides. It can therefore be concluded that the change in surface property caused by a decrease in particle size is closely linked to the electrochemical performance.

Structure and electrochemical properties of species formed as a result of Cu(II) iron adsorption onto TiO2 nanoparticles

Article Abstract:

A study was conducted to analyze sol-gel determined nanostructured TiO2 thin films and powders treated with Cu2+-containing solutions. Electrochemical techniques and electroreflection spectroscopies were utilized to carry out the analysis. Energy positions were determined using the electrolyte electroreflectance method. In addition, the adsorption of Cu2+ ions onto TiO2 nanocrystalline electrodes were performed by immersing the electrodes into Cu(Clo4)2 solutions.

Multilayered SiO2/TiO2 nanosol particles in two-dimensional aluminosilicate catalyst-support

Article Abstract:

A study was conducted to characterize a novel nanocomposite supporting a one-to-one interstratified with a montmorillonite layer and a mixed SiO2/TiO2 sol particles. The nanocomposite was prepared through the ion exchange reaction of Na+ ion in montmorillonite with positively charged SiO2/TiO2 sol particles. Experimental results indicated that the nanocomposites were highly porous.
