Potassium titanate modified with Fe3+ ions matching the stoichiometry of K1.6Fe1.6Ti6.4O16 (KFTO) was obtained by polymer complex precursor method (Pechini method). The phase composition and morphology sample were characterized using XRD, laser diffraction, SEM technique. X-ray analysis shows single-phase formation potassium a tetragonal hollandite-like structure. Rietveld used to clarify cryst...

Various morphologies of silica nanoparticles were synthesized by a microwave-assisted Pechini method. Silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in Pechini procedure. Then for preparation of polymer-matrix nanocomposites, SiO2 nanoparticles were added to poly carbonate (PC) and poly...

A novel titanium dioxide paste based on Pechini sol-gel method and nanocrystalline TiO2 powder has been successfully developed and tested. The paste enables the formation of sponge like structure of the TiO2 layer i.e. highly porous and at the same time well connected TiO2 network. The layers have been used to assemble dye sensitized solar cells (DSSC) with two ruthenium complex based dyes, N71...

The performance of LaMnxNi1-xO3±δ perovskite mixed oxides (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) which were prepared by different methods, the Pechini and sol-gel methods in the oxidation of greenhouse gases, CH4 and CO, has been investigated. All samples were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electr...

Calcium phosphates (CaPs) have broad applications in biomedicine, with the most used phases being hydroxyapatite (HAp) and β-tricalcium phosphate (β-TCP) due to their similarity natural bone. There are several methods for obtaining CaPs. However, Pechini method attracts much attention its advantages: homogeneous molecular mixing, nanocrystalline particles, low processing temperature, generating...
