Strontium titanate (STO) photocatalysts were prepared via a slightly modified Pechini sol–gel method. A unique rapid calcination technique with short exposure time was used to obtain crystalline products. The samples characterized by X-ray diffractometry, scanning electron microscopy, diffuse reflectance spectroscopy, infrared nitrogen adsorption–desorption measurements, and photoelectron spect...

In this paper, the synthesis of dicalcium silicate (C2S) via sol-gel (acid-catalyzed) process including aqueous route, non-aqueous and Pechini method is reported. The composition C2S (α, β, γ) polymorphs, by-products, amorphous content established by employing QXRD (quantitative X-ray diffraction) studies. attention has been focused to comprehend assay-amorphous relationships yield. intermediat...
